Editable Grid

v1.0.0·Added in 1.0.0

A spreadsheet-like table: typed cells edited in place, range selection, copy and paste with Excel, undo, validation, 2,000 rows at 60fps.

Click a cell to select it and the outline glides there; Shift+click, Shift+arrows or a mouse drag select a range, a row number selects the row, a column header the column, and Ctrl/⌘+A everything. Type to replace a cell, or press Enter, F2 or double-click to edit it: Enter commits and goes down (Shift+Enter up), Tab commits and goes right, wrapping to the next row (Shift+Tab left), Escape cancels, clicking elsewhere commits. The grid is one Tab stop: outside an edit, Tab moves on to the next control. Selects and dates open their picker; Space toggles checkboxes. Arrows move, Ctrl/⌘+arrows jump to the edges, Home / End go to the row ends, Ctrl/⌘+Home / End to the grid corners, PageUp / PageDown by a page. Ctrl/⌘+C copies the range as tab separated values Excel and Sheets understand, Ctrl/⌘+X cuts, Ctrl/⌘+V pastes a block from the active cell (adding rows when needed), Delete or Backspace clears, Ctrl/⌘+Z undoes and Shift+Ctrl/⌘+Z or Ctrl+Y redoes. Bad values stay in the cell with a red corner and the message under the active cell; the toolbar's error count jumps to the next one. Drag a header edge to resize a column, double-click it to fit. Hover a row number (or right-click, Shift+F10) for insert, duplicate and delete. On a phone the grid scrolls both ways with the first column frozen: tap a cell to select it, tap it again (or the row number) to edit the whole row in a bottom sheet, long press a row number for its actions.
