Make CTRL-click within a Tabulator select the row instead of editing the cell

[grelston]

Is your feature request related to a problem? Please describe.

With Tabulator.show_index=False it is very difficult to select rows within the table because clicking almost anywhere within a cell brings up the text-editing cursor. There is a very narrow (1-pixel?) strip just inside the cell border that does select instead of edit, but it is very difficult to locate using a mouse.

Describe the solution you'd like

When holding the CTRL key down, left-click would start or extend the row selection, overriding the default to edit the cell.

Describe alternatives you've considered

I like this idea a lot and had a quick look at it. We'd have to return false when the ctrlKey is pressed while in the editable callback of each column: https://github.com/holoviz/panel/blob/master/panel/models/tabulator.ts#L717

The only problem with that is that this callback does not include the click event that kicked it off so it's not totally straightforward to detect the CTRL key press and enable this functionality.
