Hi Bart.

1. The column widths is not pixel perfect. I think it don’t take the (possible) vertical scrollbar into account. Try to play with the percentages or choose pixels with a little bit left over for the scrollbar.
2. the [default cellClick function](https://discourse.nodered.org/t/ui-table-supports-ui-control/18870/24) should give you column and row information, as far as I remember or You have to write your own `cellClick`callback function for the column of your choice only. Callback functions can be sent via a `msg.ui_control` Message. There are several treads and examples how to do that perhaps this [one and the following messages](https://discourse.nodered.org/t/ui-table-supports-ui-control/18870/17)
