## Description
**Problem**
The select column of the table widget does not have a validation
property within its property pane to allow users add an isRequired
validation to the table select column.
**Solution**
Added a Validation section to the table select column's property pane,
which includes an isRequired toggle. When enabled, this feature will
trigger a visual indication (error border colour) around the select
widget if a required field is left unselected during "Add new row" or
inline editing.
Fixes#30091
