table editor: show number of rows and columns

[Wolfgang]

Hello,

following the discussion here I suggest to (more clearly) indicate the number of allocated rows and columns in the UI table editor.

I imagine something like

where the left number indicates (as now) the currently selected row, and the right number (11 in my quick example) indicates the number of all table rows.

The same might also be added for the number of total columns.

Thanks.
