+# ClientVirtualTable V2 — Server Fetching Guide
+
+This guide focuses on `fetchMode="server"` usage (Tabs 2, 2-B, 3 in `/[lng]/test/table-v2`). Client mode is unchanged from `GUIDE.md`.
+
+## Core Concepts
+- `fetchMode="server"` sets `manualPagination|manualSorting|manualFiltering|manualGrouping` to true. The table **renders what the server returns**; no client-side sorting/filtering/pagination is applied.
+- You must control table state (pagination, sorting, filters, grouping, globalFilter) in the parent and refetch on change.
+- Provide `rowCount` (and optionally `pageCount`) so the pagination footer is accurate.
+- Export uses the current row model; in server mode it only exports the loaded page unless you fetch everything yourself.
+
+## Minimal Wiring (Factory Service)
+```tsx
+const [pagination, setPagination] = useState({ pageIndex: 0, pageSize: 10 });
+const [sorting, setSorting] = useState([]);
+const [columnFilters, setColumnFilters] = useState([]);
+const [globalFilter, setGlobalFilter] = useState("");
+const [data, setData] = useState([]);
+const [rowCount, setRowCount] = useState(0);
+const [loading, setLoading] = useState(false);
+
+useEffect(() => {
+  const run = async () => {
+    setLoading(true);
+    const res = await getTableData({
+      pagination,
+      sorting,
+      columnFilters,
+      globalFilter,
+    });
+    setData(res.data);
+    setRowCount(res.totalRows);
+    setLoading(false);
+  };
+  run();
+}, [pagination, sorting, columnFilters, globalFilter]);
+
+<ClientVirtualTable
+  fetchMode="server"
+  data={data}
+  rowCount={rowCount}
+  columns={columns}
+  isLoading={loading}
+  enablePagination
+  pagination={pagination}
+  onPaginationChange={setPagination}
+  sorting={sorting}
+  onSortingChange={setSorting}
+  columnFilters={columnFilters}
+  onColumnFiltersChange={setColumnFilters}
+  globalFilter={globalFilter}
+  onGlobalFilterChange={setGlobalFilter}
+/>
+```
+
+## Using `createTableService` (Pattern 2)
+- Import `createTableService` in a server action and pass `columns` (accessorKey-based) plus schema/db.
+- The adapter maps `sorting`, `columnFilters`, `globalFilter`, `pagination` to Drizzle query parts.
+- Returned shape: `{ data, totalRows, pageCount }`. Always forward `totalRows` to the client.
+
+## Custom Service (Pattern 3)
+- Build custom joins manually; still read `tableState` for pagination/sorting/filtering if you need them.
+- For sorting: map `tableState.sorting` IDs to your joined columns; provide a default order if none is set.
+- Grouping in custom services requires manual implementation (see `getOrderTableDataGroupedByStatus` pattern).
+
+## Server Grouping (Pattern 2-B)
+- Only columns marked `meta.serverGroupable` in server column defs should be used.
+- Group headers are fetched via DB `GROUP BY`; expanded rows are fetched per group.
+- When grouping is active, the table may render a custom grouped view instead of the virtual table; ensure your fetcher returns either `{ groups }` or `{ data, totalRows }`.
+
+## Presets in Server Mode
+- Presets store: sorting, columnFilters, globalFilter, columnVisibility, columnPinning, columnOrder, grouping, pageSize.
+- Loading a preset triggers the table’s `set*` APIs; parent `on*Change` handlers refetch with the restored state.
+- The component resets pageIndex to 0 when applying a preset to avoid out-of-range requests after pageSize changes.
+- Use unique `tableKey` per screen to avoid clashing presets across pages.
+
+## Common Pitfalls
+- Forgetting `rowCount` → pagination shows wrong totals.
+- Not reacting to `sorting`/`filters`/`grouping` changes in your effect → UI toggles with no data change.
+- Mapping `sorting` IDs to columns incorrectly in custom services → server ignores the sort.
+- Mixing client-side models with server mode: do not enable client `getSortedRowModel`/`getFilteredRowModel` for server fetches (the component already skips them when `fetchMode="server"`).
+
+## Feature Matrix (Server Mode)
+- Sorting: Supported; must be implemented in the server fetcher.
+- Filtering: Supported; column filters/global filter forwarded; implement in server.
+- Pagination: Supported; manual; provide `rowCount`.
+- Grouping: Client grouping is off in server mode; implement via server `GROUP BY` or custom grouped view.
+- Column show/hide, pinning, reorder: Client-side only; state is preserved and sent to presets but does not affect server queries unless you opt to read it.
+- Export: Exports the currently loaded rows; fetch all data yourself for full exports.
+
+## Debug Checklist
+- Confirm `fetchMode="server"` and `rowCount` are set.
+- Verify the parent effect depends on `pagination`, `sorting`, `columnFilters`, `globalFilter`, and (if used) `grouping`.
+- In custom services, console/log the incoming `tableState` to confirm the UI is sending the intended state.

+# ClientVirtualTable V3 가이드 (한국어)
+
+`components/client-table-v2` 테이블 컴포넌트와 `fetchMode="server"` 사용 시 주의점을 정리했습니다.
+
+## 모듈 맵
+- `client-virtual-table.tsx`: 코어 테이블(가상 스크롤, 컬럼 DnD, 핀/숨김, 프리셋, 툴바, 페이지네이션).
+- `client-table-column-header.tsx`: 헤더 셀(정렬 토글, 필터 UI, 컨텍스트 메뉴: 핀/숨김/그룹/재정렬).
+- `client-table-toolbar.tsx` (client-table): 검색, 내보내기, 뷰 옵션, 프리셋 엔트리.
+- `client-table-view-options.tsx` (client-table): 컬럼 표시/숨김 토글.
+- `client-table-filter.tsx`: 컬럼 필터 UI(text/select/boolean).
+- `client-table-preset.tsx`: `tableKey`+사용자별 프리셋 저장/불러오기/삭제.
+- 기타: `export-utils`, `import-utils`, `ClientDataTablePagination`(client-data-table).
+- 서버 헬퍼: `adapter/create-table-service.ts`, `adapter/drizzle-table-adapter.ts`.
+- 타입: `types.ts`, `preset-types.ts`.
+
+## 핵심 동작 (ClientVirtualTable)
+- 가상 스크롤: `height` 필수, `estimateRowHeight` 기본 40.
+- DnD: 컬럼 재배치, 핀 섹션 간 이동 시 핀 상태 동기화.
+- 핀/숨김/순서: 클라이언트 상태(`columnVisibility`, `columnPinning`, `columnOrder`).
+- 정렬/필터/페이지네이션/그룹핑
+  - `fetchMode="client"`: TanStack 모델 사용.
+  - `fetchMode="server"`: manual 플래그 on, 클라이언트 모델 skip → **서버가 정렬/필터/페이징된 결과를 반환해야 함**.
+- 내보내기: 현재 렌더된 행 기준. 서버 모드에서 전체 내보내기는 직접 `onExport`로 구현 필요.
+- 프리셋: `enableUserPreset`+`tableKey` 설정 시 표시. 불러올 때 pageIndex를 0으로 리셋해 서버 모드에서 범위 오류 방지.
+
+## 주요 Props
+- `fetchMode`: `"client"` | `"server"` (기본 `"client"`).
+- 데이터: `data`, `rowCount?`, `pageCount?`.
+- 상태/핸들러:
+  - 페이지: `pagination`, `onPaginationChange`, `enablePagination`, `manualPagination?`.
+  - 정렬: `sorting`, `onSortingChange`.
+  - 필터: `columnFilters`, `onColumnFiltersChange`, `globalFilter`, `onGlobalFilterChange`.
+  - 그룹핑: `grouping`, `onGroupingChange`, `expanded`, `onExpandedChange`, `enableGrouping`.
+  - 표시/핀/순서: `columnVisibility`, `columnPinning`, `columnOrder` 및 각 onChange.
+  - 선택: `enableRowSelection`, `enableMultiRowSelection`, `rowSelection`, `onRowSelectionChange`.
+- UX: `actions`, `customToolbar`, `enableExport`, `onExport`, `renderHeaderVisualFeedback`, `getRowClassName`, `onRowClick`.
+- 프리셋: `enableUserPreset`, `tableKey`.
+- 메타: `meta`, `getRowId`.
+
+## 서버 페칭 패턴
+### 패턴 1: 클라이언트 모드
+- `fetchMode="client"`, 전체 데이터 전달. 정렬/필터/그룹핑은 브라우저에서 처리.
+
+### 패턴 2: Factory Service (`createTableService`)
+- 서버 액션: `createTableService({ db, schema, columns, defaultWhere?, customQuery? })`.
+- 어댑터가 `sorting`, `columnFilters`, `globalFilter`, `pagination`, `grouping`을 Drizzle `where/orderBy/limit/offset/groupBy`로 변환.
+- 반환 `{ data, totalRows, pageCount }` → 클라이언트에서 `rowCount` 설정 필수.
+- 클라이언트: `pagination/sorting/columnFilters/globalFilter` 제어 후 deps로 `useEffect` 재호출.
+
+### 패턴 2-B: 서버 그룹핑
+- `getProductTableDataWithGrouping` 예시: `grouping` 없으면 일반 페칭, 있으면 DB `GROUP BY` 후 `{ groups }` 반환.
+- 서버 그룹핑 가능한 컬럼(`meta.serverGroupable`)만 사용.
+- 그룹 확장 시 그룹 키별 하위 행을 추가 조회, 그룹 변경 시 확장 상태 초기화.
+- 그룹뷰 렌더 시 가상 테이블 대신 커스텀 블록을 사용할 수 있음.
+
+### 패턴 3: 커스텀 서비스
+- 조인/파생 컬럼용. `tableState`를 읽어 정렬 ID를 조인 컬럼에 매핑, 정렬 없을 때 기본 정렬 제공.
+- 필터/글로벌 필터는 직접 구현해야 함.
+- 그룹핑도 수동 구현(`getOrderTableDataGroupedByStatus` 참고).
+
+## 상태 → 쿼리 매핑 (서버)
+- 정렬: `tableState.sorting`(id, desc) → DB 컬럼 매핑, 모르는 id는 무시.
+- 필터: 텍스트(ilike), 불리언, 숫자, 범위[min,max], 다중선택(IN) 지원.
+- 글로벌 필터: 매핑된 컬럼 OR ilike.
+- 페이지: pageIndex/pageSize → limit/offset, `rowCount` 반환.
+- 그룹핑: 지원 컬럼만 `GROUP BY`.
+
+## 프리셋 (서버 호환)
+- 저장: sorting, columnFilters, globalFilter, columnVisibility, columnPinning, columnOrder, grouping, pageSize.
+- 불러오기: `table.set*` 호출 + pageIndex 0 리셋 → 상위 `on*Change` 핸들러에서 재페칭.
+- 화면별 고유 `tableKey` 사용 권장. 세션 필요.
+
+## 기능 매트릭스 (서버 모드)
+- 정렬: 지원 (서버 구현 필요)
+- 필터: 지원 (서버 구현 필요)
+- 페이지네이션: 지원 (manual, `rowCount` 필요)
+- 그룹핑: 자동 미지원, 서버 그룹핑 또는 커스텀 뷰로 구현
+- 컬럼 숨김/핀/순서: 클라이언트 전용(시각용), 서버 쿼리에 자동 반영 안 함
+- 내보내기: 로드된 행만; 전체 내보내기는 커스텀 `onExport` 필요
+
+## 구현 팁
+- `fetchMode="server"`일 때 `rowCount` 꼭 설정.
+- `pagination/sorting/columnFilters/globalFilter/(grouping)` 변경 시마다 재페칭.
+- 정렬 없을 때 서버 기본 정렬을 지정.
+- 그룹 변경 시 확장 상태 초기화.
+- `height`를 항상 지정(가상 스크롤 컨테이너 필요).
+
+## 빠른 예시
+- 클라이언트: `fetchMode="client"`, 전체 데이터 전달, 그룹핑 옵션 사용 가능.
+- Factory 서버: `fetchMode="server"`, `createTableService`, 제어형 상태 + `rowCount`.
+- 서버 그룹핑: `grouping`에 따라 `{ groups }` vs `{ data }` 반환, `serverGroupable` 컬럼만 허용.
+- 커스텀 조인: 정렬 ID 직접 매핑, 필터/글로벌 직접 적용, `rowCount` 반환.

+# ClientVirtualTable V3 Guide
+
+This guide documents the table components in `components/client-table-v2`, with an emphasis on server fetching (`fetchMode="server"`) and how supporting components fit together.
+
+## Module Map
+- `client-virtual-table.tsx`: Core table (virtualized, DnD columns, pin/hide, presets hook point, toolbar, pagination).
+- `client-table-column-header.tsx`: Header cell with sort toggle, filter UI, context menu (hide/pin/group/reorder hook).
+- `client-table-toolbar.tsx` (from `components/client-table`): Search box, export button, view options, preset entry point.
+- `client-table-view-options.tsx` (from `components/client-table`): Column visibility toggles.
+- `client-table-filter.tsx`: Column filter UI (text/select/boolean).
+- `client-table-preset.tsx`: Save/load/delete presets per `tableKey` + user.
+- `client-table-save-view.tsx`, `client-table-preset.tsx`, `client-table-toolbar.tsx`: Preset and view controls.
+- `client-virtual-table` dependencies: `ClientDataTablePagination` (`components/client-data-table`), `export-utils`, `import-utils`.
+- Server helpers: `adapter/create-table-service.ts`, `adapter/drizzle-table-adapter.ts`.
+- Types: `types.ts`, `preset-types.ts`.
+
+## Core Behaviors (ClientVirtualTable)
+- Virtualization: `height` is required; `estimateRowHeight` defaults to 40.
+- Drag & Drop: Columns reorder across pin sections; drag between pin states updates pinning.
+- Pin/Hide/Reorder: Managed client-side; state is exposed via `columnVisibility`, `columnPinning`, `columnOrder`.
+- Sorting/Filtering/Pagination/Grouping:
+  - `fetchMode="client"`: uses TanStack models (`getSortedRowModel`, `getFilteredRowModel`, `getPaginationRowModel`, etc.).
+  - `fetchMode="server"`: sets manual flags true and skips client models; **server must return already-sorted/filtered/paged data**.
+- Export: Uses current row model; in server mode it exports only the loaded rows unless you supply all data yourself via `onExport`.
+- Presets: When `enableUserPreset` and `tableKey` are set, toolbar shows the preset control; loading a preset resets pageIndex to 0 to avoid invalid pages on server mode.
+
+## Key Props (ClientVirtualTable)
+- `fetchMode`: `"client"` | `"server"` (default `"client"`).
+- Data: `data`, `rowCount?`, `pageCount?`.
+- State + handlers (controlled or uncontrolled):
+  - Pagination: `pagination`, `onPaginationChange`, `enablePagination`, `manualPagination?`.
+  - Sorting: `sorting`, `onSortingChange`.
+  - Filters: `columnFilters`, `onColumnFiltersChange`, `globalFilter`, `onGlobalFilterChange`.
+  - Grouping: `grouping`, `onGroupingChange`, `expanded`, `onExpandedChange`, `enableGrouping`.
+  - Visibility/Pinning/Order: `columnVisibility`, `onColumnVisibilityChange`, `columnPinning`, `onColumnPinningChange`, `columnOrder`, `onColumnOrderChange`.
+  - Selection: `enableRowSelection`, `enableMultiRowSelection`, `rowSelection`, `onRowSelectionChange`.
+- UX: `actions`, `customToolbar`, `enableExport`, `onExport`, `renderHeaderVisualFeedback`, `getRowClassName`, `onRowClick`.
+- Presets: `enableUserPreset`, `tableKey`.
+- Meta: `meta`, `getRowId`.
+
+## Server Fetching Patterns
+### Pattern 1: Client-Side (baseline)
+- `fetchMode="client"`, pass full dataset; TanStack handles sorting/filtering/grouping locally.
+
+### Pattern 2: Factory Service (`createTableService`)
+- Server action: `createTableService({ db, schema, columns, defaultWhere?, customQuery? })`.
+- The adapter maps `sorting`, `columnFilters`, `globalFilter`, `pagination`, `grouping` → Drizzle `where`, `orderBy`, `limit`, `offset`, `groupBy`.
+- Returns `{ data, totalRows, pageCount }`; always forward `totalRows` to the client and wire `rowCount`.
+- Client wiring: control `pagination`, `sorting`, `columnFilters`, `globalFilter`; refetch in `useEffect` on those deps.
+
+### Pattern 2-B: Server Grouping
+- Uses `getProductTableDataWithGrouping` sample: if `grouping` is empty → normal server fetch; else returns `{ groups }` built from DB `GROUP BY`.
+- Columns must be marked `meta.serverGroupable` in server column defs.
+- Expanded groups fetch child rows per group key; grouping change clears expanded state.
+- UI may render a custom grouped view (not the virtual table) when grouped.
+
+### Pattern 3: Custom Service
+- For joins/derived columns: read `tableState` and manually map `sorting` IDs to joined columns; supply a default order when no sort is present.
+- Filtering/global filter are not automatic—implement them if needed.
+- Grouping is manual; see `getOrderTableDataGroupedByStatus` pattern for a grouped response shape.
+
+## State → Query Mapping (Server)
+- Sorting: `tableState.sorting` (id, desc) → map to DB columns; ignore unknown ids.
+- Filters: `columnFilters` supports text (ilike), boolean, number, range `[min,max]`, multi-select (IN).
+- Global filter: ilike OR across mapped columns.
+- Pagination: pageIndex/pageSize → limit/offset; return `rowCount`.
+- Grouping: `grouping` → `GROUP BY` for supported columns only.
+
+## Presets (Server-Friendly)
+- Saved keys: sorting, columnFilters, globalFilter, columnVisibility, columnPinning, columnOrder, grouping, pageSize.
+- On load: applies `table.set*` and resets pageIndex to 0; parent `on*Change` handlers should trigger refetch.
+- Use unique `tableKey` per screen to avoid collisions; requires authenticated session.
+
+## Feature Matrix (Server Mode)
+- Sorting: Yes—server implemented.
+- Filtering: Yes—server implemented.
+- Pagination: Yes—manual; provide `rowCount`.
+- Grouping: Not automatic; implement via server grouping or custom grouped view.
+- Column hide/pin/reorder: Client-only (visual); does not change server query unless you opt to read it.
+- Export: Only current rows unless you provide `onExport` with full data.
+
+## Implementation Tips
+- Always set `rowCount` when `fetchMode="server"`.
+- Refetch on `pagination`, `sorting`, `columnFilters`, `globalFilter`, and `grouping` (if used).
+- Provide a default sort on the server when `sorting` is empty.
+- Reset `expanded` or group expand state when grouping changes in server grouping flows.
+- Ensure `height` is set; virtualization needs a scroll container.
+
+## Quick Examples
+- Client: `fetchMode="client"` with `data` = full list; optional grouping enabled.
+- Factory server: `fetchMode="server"`, `createTableService` action, controlled state with `rowCount`.
+- Server grouping: `grouping` drives `{ groups }` vs `{ data }` response; only `serverGroupable` columns allowed.
+- Custom join: Manually map `sorting` ids; apply filters/global; return `rowCount`.
