corner
        anchor.setCol1(cell.getColumnIndex() + 1); //the box of the comment
starts at this given column...
        anchor.setCol2(cell.getColumnIndex() + 3); //...and ends at that
given column
        anchor.setRow1(rowIdx + 1); //one row below the cell...
        anchor.setRow2(rowIdx + 5); //...and 4 rows high
