rows.apply needs a rowKey to identify rows; without one, updates and removals cannot be matched.

What happened

A keyed diff names the rows it changes, and this grid identifies rows by index because no rowKey was declared. There is no way to match an update or a removal to a row, so those parts of the change cannot be applied.

The fix

Declare rowKey - the field that identifies a row, or a function returning it. Keyed identity is what the live-update, diff, selection-stability and comment features all need.

The smallest fix

createGrid(el, { rowKey: 'id' });
