Describe the bug

When merge_duplicate_headers= True there is a large amount of whitespace to the right of the table. It is visible when going to the boundary of the scroll bar. This issue is present with both dash_table.DataTable and ddk.DataTable

Expected behavior
The boundary is expected to be at the end of the last column of the dataTable.

Screenshots
Here you can see the whitespace
