Add TableRow::col_sense

[max-huster]

Add TableRow::col_sense which does the same as TableRow::col but allows to specify a Sense. It allows for detecting clicks on rows

Closes Discussion #1519

Great addition, but I would like to see two more things:

A) An example using this
B) A hover-effect on the row (e.g. a framing of it like we have for Button)

@emilk Could you provide any hints on how to do that?

I've created a PoC app that uses TableRow::col_sense. You click on a row and its labels change background color:

I am struggling to figure out

• how to highlight the whole row (not just text labels) and
• how to apply the framing effect to a row...

I would appreciate some hints. 😇

I'm trying to implement framing for table rows. The desired effect should look like this (light grey background for the hovered-over table row; light blue for the selected row):

I understand how to frame a button:

1. determine the size,
2. allocate,
3. interact,
4. paint the background,
5. paint the rest of the 🦉 button over the background.

But table row is different. A row consists of cells. The rectangle occupied by the row is not known until all the cells of this row are painted. And once they are painted, it is already too late to paint the background! We'll be painting over the cells.

Like on this demo here, where I'm painting over the middle cell:
