Angular Data Grid Cell Selection

People who work with tabular data reach for a spreadsheet’s muscle memory: drag across a block of numbers, hit Ctrl+C, paste it somewhere else. cellSelection gives the grid that, on top of the same active-cell substrate keyboard navigation already provides.

Cell selection

Select the way you would in a spreadsheet — click a cell, drag across a block, shift-click a far corner, or hold Shift and press an arrow. Ctrl/Cmd+A selects everything, and Ctrl/Cmd+C copies the range: try it and paste into a spreadsheet.

import { Component } from '@angular/core'
import { DataGridComponent } from '@coreui/angular-data-grid'
import type { DataGridColumn, DataGridItem } from '@coreui/angular-data-grid'

@Component({
  selector: 'docs-data-grid-cell-selection-example',
  imports: [DataGridComponent],
  template: `
    <c-data-grid
      [columns]="columns"
      [items]="items"
      [cellSelection]="true"
      [sorting]="false"
      [virtualization]="false"
    />
  `
})
export class DataGridCellSelectionExample {
  readonly columns: DataGridColumn[] = [
    { key: 'quarter', label: 'Quarter' },
    { key: 'emea', label: 'EMEA' },
    { key: 'amer', label: 'AMER' },
    { key: 'apac', label: 'APAC' }
  ]
readonly items: DataGridItem[] = [
    {
 quarter: 'Q1', emea: 128400, amer: 214900, apac: 96300
},
    {
 quarter: 'Q2', emea: 141200, amer: 208700, apac: 104800
},
    {
 quarter: 'Q3', emea: 152900, amer: 226400, apac: 118200
},
    {
 quarter: 'Q4', emea: 167300, amer: 241800, apac: 129600
}
  ]
}

Interactions

cellSelection implies cellNavigation: the active cell is the grid’s single focus owner, and the selection anchors on it rather than tracking a second one.

The clipboard format

The copy is tab-separated — the format spreadsheets read back as columns. Rows are separated by newlines, and disjoint rectangles by a blank line. A value containing a tab, a newline or a quote is quoted the way TSV consumers expect.

Cells copy as they are displayed: a column’s formatter runs first, so a formatted date pastes as the date on screen rather than its underlying value.

Each copy fires (cellCopy) with the exact text written, so you can mirror it somewhere else or count it.

The grid uses the async clipboard API and falls back to a hidden textarea where that is unavailable or denied — both work because the copy runs inside the key press that asked for it.

Bundle cost

Cell selection is the largest single feature in the grid: cellSelectionFeature adds about 4 KB gzipped to the TanStack core. A grid that does not need it can drop that by naming a smaller feature set — which is exactly what the lite build does.
