Grid cellClick event emits incorrect column index when using rowSpan
Description
The cellClick event returns the wrong column index when a cell spans multiple rows using rowSpan; the issue seems to appear in the column rendered after the row-spanned one. This behavior also seems to break the editing.
Steps To Reproduce
Clicking the first two cells in the "UnitPrice" column shows that the cellClick event returns column index 2 for the first cell (correct) and column index 1 for the second (incorrect), due to the applied rowSpan.

When you click on the second cell in the "UnitPrice" column, the editor is not displayed.
