When I set a table column’s element type to Checkbox, the header cell is always a text box. This limits design flexibility, especially when I want to show a “Select All” checkbox in the header.

I would like the header cell to support two options when the column element type is Checkbox:

Header as a Checkbox

Useful for representing a “Select All” or master checkbox

Header as a Textbox

Useful when the header label should be text (e.g., “Select”, “Mark”, “Choose”)

This would give designers more control over table layouts involving selection columns.
