Canvas based data grid web component. Capable of displaying millions of contiguous hierarchical rows and columns without paging or loading, on a single canvas element.
Add a new attribute, allowGridSizeChangeOnPaste (which is false by default). If it's set to true and pasted data is bigger than the grid, new rows or columns will be created as needed. Please see the screen recording.
This is slow for big datasets because a) .addRow() calls .refresh() b) on each cell pasted .selectCell() is called. So there's plenty of room for optimization.
Fixes issue #552.
