Fix VCD datagrid dropdown actions column width

When datagrid is empty or the columns are rendered before the grid is populated with data the width of the dropdown actions column is wider than expected

Testing Done:
Test in the VCD project (no way to test it in the components examples since the issue is a corner case)
