Bug - Table - High Visibility Accessibility Issue

[ArathyKumar]

Describe the problem
An unexpected table header element transformation when implementing the 'select all' functionality for checkboxes. Upon attaching a 'select' event handler to the <Th> element within the checkbox column's header, the <Th> element is converted to a <Td> element in the DOM.
Compromising the table structure creates an accessibility issue as there is no table header(<Th>) for a column.

How do you reproduce the problem?
Please try to inspect the structure of this table in the DOM.

Expected behaviour
The table structure should not be altered on rendering in the DOM.
