+# ARIA Grid with CDK Table Integration
+
+This module provides ARIA grid directives that work seamlessly with Angular CDK Table, solving the DI tree issue that occurs when using templates and portals.
+
+## The Problem
+
+When using ARIA grid directives with CDK table, the `ngGridCell` directive fails to find the `GRID_ROW` provider because CDK table renders cells through templates and portals, which breaks the normal Angular DI tree.
+
+## The Solution
+
+This implementation provides multiple approaches to solve the DI issue:
+
+### 1. Simple Row Provider (Recommended)
+
+Use the `cdkGridRowProvider` directive on your table rows:
+
+```typescript
+@Component({
+  imports: [CdkTableModule, Grid, GridRow, GridCell, CdkGridRowProvider],
+  template: `
+    <table ngGrid cdk-table [dataSource]="data">
+      @for (column of columns; track column) {
+        <ng-container [cdkColumnDef]="column">
+          <th ngGridCell cdk-header-cell *cdkHeaderCellDef>{{ column }}</th>
+          <td ngGridCell cdk-cell *cdkCellDef="let row">{{ row[column] }}</td>
+        </ng-container>
+      }
+      <tr ngGridRow cdkGridRowProvider cdk-header-row *cdkHeaderRowDef="columns"></tr>
+      <tr ngGridRow cdkGridRowProvider cdk-row *cdkRowDef="let row; columns: columns"></tr>
+    </table>
+  `
+})
+export class MyTable {
+  data = [
+    { name: 'John', age: 30 },
+    { name: 'Jane', age: 25 }
+  ];
+  columns = ['name', 'age'];
+}
+```
+
+### 2. DOM-based Fallback
+
+The `GridCell` directive automatically falls back to DOM traversal when DI fails, so it works without additional configuration in most cases.
+
+## Key Features
+
+- **Automatic DI Fallback**: GridCell automatically searches the DOM hierarchy when DI fails
+- **CDK Table Integration**: Seamless integration with existing CDK table implementations  
+- **Minimal Code Changes**: Only requires adding `cdkGridRowProvider` to row elements
+- **Performance Optimized**: Uses efficient DOM traversal and caching
+- **Type Safe**: Full TypeScript support with proper typing
+
+## API Reference
+
+### Directives
+
+- `Grid` - Main grid container (`[ngGrid]`)
+- `GridRow` - Grid row (`[ngGridRow]`) 
+- `GridCell` - Grid cell (`[ngGridCell]`)
+- `CdkGridRowProvider` - CDK table row provider (`[cdkGridRowProvider]`)
+
+### Tokens
+
+- `GRID_ROW` - Injection token for grid row instances
+
+## Migration Guide
+
+To migrate existing CDK tables to use ARIA grid:
+
+1. Add `ngGrid` to your table element
+2. Add `ngGridRow` to your row templates  
+3. Add `ngGridCell` to your cell templates
+4. Add `cdkGridRowProvider` to CDK row templates
+5. Import the required directives in your component
+
+The solution is backward compatible and doesn't affect existing CDK table functionality.
