In GridElement there are: getFooterCell(int columnIndex) and getHeaderCell(int columnIndex)
Then there is a method getHeaderCellContent(int rowIndex, int columnIndex)

Although, first method (only with columnIndex) makes sense as there could be the main (or the only one) footer and the main header, but as we all know: Grid can have multiple headers or footers.

We need to introduce into the Testbench:

• getFooterCell(int rowIndex, int columnIndex)
• getHeaderCell(int rowIndex, int columnIndex)

or

• getHeader(int rowIndex)
• getFooter(int rowIndex)
