Proposition
When the table header is disabled, make the available row height use the table height and do not reduce it by the header height.

Result
When a table's header is disabled, the table height will be what was specified and not shortened by header height.

Use Case
The table's height dimension is proportional or equal to parent element, and when header is disabled the table looks short of the expected height.
