+
+### Advanced Filtering
+```tsx
+import { Button } from "@/components/ui/button"
+import {
+  DropdownMenu,
+  DropdownMenuCheckboxItem,
+  DropdownMenuContent,
+  DropdownMenuTrigger,
+} from "@/components/ui/dropdown-menu"
+
+// Column visibility toggle
+<DropdownMenu>
+  <DropdownMenuTrigger asChild>
+    <Button variant="outline" className="ml-auto">
+      Columns <ChevronDown className="ml-2 h-4 w-4" />
+    </Button>
+  </DropdownMenuTrigger>
+  <DropdownMenuContent align="end">
+    {table
+      .getAllColumns()
+      .filter((column) => column.getCanHide())

+          </DropdownMenuCheckboxItem>

+</DropdownMenu>
+
+// Global filter

+<Input
+  placeholder="Search all columns..."
+  value={globalFilter ?? ""}
+  onChange={(event) => setGlobalFilter(event.target.value)}
+  className="max-w-sm"
+/>
+```
+
+### Data Formatting Utilities
+```tsx
+// Currency formatter
+export const formatCurrency = (amount: number, currency = 'USD') => {
+  return new Intl.NumberFormat('en-US', {
+    style: 'currency',
+    currency,
+  }).format(amount)
+}
+
+// Date formatter
+export const formatDate = (date: Date | string, options?: Intl.DateTimeFormatOptions) => {
+  const defaultOptions: Intl.DateTimeFormatOptions = {
+    year: 'numeric',
+    month: 'short',
+    day: 'numeric',
+  }
+  
+  return new Intl.DateTimeFormat('en-US', { ...defaultOptions, ...options })
+    .format(new Date(date))
+}
+
+// Number formatter with suffixes
+export const formatNumber = (num: number, precision = 1) => {
+  const suffixes = ['', 'K', 'M', 'B', 'T']
+  const suffixNum = Math.floor(Math.log10(Math.abs(num)) / 3)
+  const shortValue = (num / Math.pow(1000, suffixNum))
+  
+  return shortValue.toFixed(precision) + suffixes[suffixNum]
+}
+
+// Status badge component
+export const StatusBadge = ({ status }: { status: string }) => {
+  const variants = {
+    active: "default",
+    inactive: "secondary",
+    pending: "outline",
+    error: "destructive",
+  } as const
+
+  return (
+    <Badge variant={variants[status as keyof typeof variants] || "secondary"}>
+      {status}
+    </Badge>
+  )
+}
+```
+
+## Chart Integration
+
+### Recharts Example
+```tsx
+import {
+  LineChart,
+  Line,
+  XAxis,
+  YAxis,
+  CartesianGrid,
+  Tooltip,
+  ResponsiveContainer,
+  PieChart,
+  Pie,
+  Cell,
+} from "recharts"
+import { Card, CardContent, CardDescription, CardHeader, CardTitle } from "@/components/ui/card"
+
+const data = [
+  { name: 'Jan', value: 400 },
+  { name: 'Feb', value: 300 },
+  { name: 'Mar', value: 600 },
+  { name: 'Apr', value: 800 },
+  { name: 'May', value: 500 },
+]
+
+export function RevenueChart() {
+  return (
+    <Card>
+      <CardHeader>
+        <CardTitle>Revenue Over Time</CardTitle>
+        <CardDescription>Monthly revenue for the past 5 months</CardDescription>
+      </CardHeader>
+      <CardContent>
+        <ResponsiveContainer width="100%" height={300}>
+          <LineChart data={data}>
+            <CartesianGrid strokeDasharray="3 3" />
+            <XAxis 
+              dataKey="name" 
+              tick={{ fontSize: 12 }}
+              tickLine={{ stroke: '#ccc' }}
+            />
+            <YAxis 
+              tick={{ fontSize: 12 }}
+              tickLine={{ stroke: '#ccc' }}
+            />
+            <Tooltip 
+              contentStyle={{
+                backgroundColor: 'hsl(var(--background))',
+                border: '1px solid hsl(var(--border))',
+                borderRadius: '6px'
+              }}
+            />
+            <Line 
+              type="monotone" 
+              dataKey="value" 
+              stroke="hsl(var(--primary))" 
+              strokeWidth={2}
+            />
+          </LineChart>
+        </ResponsiveContainer>
+      </CardContent>
+    </Card>
+  )
+}
+```
+
+### Custom Progress Components
+```tsx
+import { Progress } from "@/components/ui/progress"
+
+export function DataProgress({ 
+  value, 
+  max = 100, 
+  label,
+  showValue = true 
+}: {
+  value: number
+  max?: number
+  label?: string
+  showValue?: boolean
+}) {
+  const percentage = (value / max) * 100
+
+  return (
+    <div className="space-y-2">
+      <div className="flex justify-between text-sm">
+        {label && <span className="font-medium">{label}</span>}
+        {showValue && (
+          <span className="text-muted-foreground">
+            {value} / {max}
+          </span>
+        )}
+      </div>
+      <Progress value={percentage} />
+    </div>
+  )
+}
+
+// Usage in table cell
+{
+  accessorKey: "progress",
+  header: "Completion",
+  cell: ({ row }) => (
+    <DataProgress
+      value={row.getValue("progress")}
+      max={100}
+      label="Progress"
+    />
+  ),
+}
+```
+
+## Advanced Features
+
+### Virtual Scrolling for Large Datasets
+```tsx
+import { useVirtualizer } from '@tanstack/react-virtual'
+
+export function VirtualizedTable({ data }: { data: any[] }) {
+  const parentRef = React.useRef<HTMLDivElement>(null)
+
+  const virtualizer = useVirtualizer({
+    count: data.length,
+    getScrollElement: () => parentRef.current,
+    estimateSize: () => 50, // Row height
+    overscan: 10,
+  })
+
+  return (
+    <div
+      ref={parentRef}
+      className="h-96 overflow-auto"
+    >
+      <div
+        style={{
+          height: `${virtualizer.getTotalSize()}px`,
+          width: '100%',
+          position: 'relative',
+        }}
+      >
+        {virtualizer.getVirtualItems().map((virtualRow) => (
+          <div
+            key={virtualRow.key}
+            style={{
+              position: 'absolute',
+              top: 0,
+              left: 0,
+              width: '100%',
+              height: `${virtualRow.size}px`,
+              transform: `translateY(${virtualRow.start}px)`,
+            }}
+          >
+            {/* Row content */}
+            <div className="flex items-center p-4 border-b">
+              {data[virtualRow.index].name}
+            </div>
+          </div>
+        ))}
+      </div>
+    </div>
+  )
+}
+```
+
+### Export Functionality
+```tsx
+import { Button } from "@/components/ui/button"
+import { Download } from "lucide-react"
+
+export function ExportButton({ data, filename = 'data' }: {
+  data: any[]
+  filename?: string
+}) {
+  const exportToCSV = () => {
+    if (!data.length) return
+
+    const headers = Object.keys(data[0]).join(',')
+    const rows = data.map(row => 
+      Object.values(row).map(value => 
+        typeof value === 'string' ? `"${value}"` : value
+      ).join(',')
+    ).join('\n')
+
+    const csv = `${headers}\n${rows}`
+    const blob = new Blob([csv], { type: 'text/csv' })
+    const url = URL.createObjectURL(blob)
+    
+    const link = document.createElement('a')
+    link.href = url
+    link.download = `${filename}.csv`
+    link.click()
+    
+    URL.revokeObjectURL(url)
+  }
+
+  return (
+    <Button variant="outline" onClick={exportToCSV}>
+      <Download className="mr-2 h-4 w-4" />
+      Export CSV
+    </Button>
+  )
+}
+```
+
+## Best Practices
+
+1. **Performance**
+   - Use virtualization for large datasets (1000+ rows)
+   - Implement proper memoization with React.memo
+   - Debounce search/filter inputs
+   - Use server-side pagination when possible
+
+2. **Accessibility**
+   - Include proper ARIA labels for sortable columns
+   - Ensure keyboard navigation works
+   - Provide screen reader announcements for data changes
+   - Use semantic table markup
+
+3. **User Experience**
+   - Show loading states during data fetching
+   - Provide empty state messages
+   - Include pagination controls
+   - Make columns resizable and sortable
+   - Implement persistent column preferences
+
+4. **Data Integrity**
+   - Validate data types before rendering
+   - Handle null/undefined values gracefully
+   - Provide fallback values for missing data
+   - Include error boundaries for chart components
+
+Remember: Data should tell a story - make it clear, accessible, and actionable!
