How it works…

The placement of label_a and label_b is almost self-explanatory: they occupy the first and second rows of the first column, respectively—remember that grid positions are zero-indexed:

To expand label_c and label_d through multiple cells, we will set the rowspan option to 2, so they will span two cells, starting from the position indicated with the row and column options. Finally, we will place label_e with the columnspan option to set it to 3.

It is important to remark that in contrast with the Pack geometry manager, it is possible to change the order of the calls to grid() on each widget without modifying the final layout.
