Most likely they are using modulo (even = rowIndex % 2 == 0). Does it really matter? IMO: no. E.g. 0 % 2 == 0 (even) 1 % 2 == 0 (odd) 2 % 2 == 0 (even) ... for (int i = 1; i < size; i++) { if (i % 2 == 0) { final HTMLTable.RowFormatter formatter = gridex.getRowFormatter(); formatter.addStyleName(i, "kw-sortable-dark"); } }
