The grid geometry manager creates a table-like layout.
So to arrange a widget with the grid manager, use the
grid function with the parameters of row and column
number (starting from zero). There is one keyword parameter :sticky
which governs the widget alignment within its table cell. Its a string containing
any combination of ``n'' ``e'' ``s'' and ``w''.
The behaviour of the single rows and columns of the grid are controlled by the
grid-rowconfigure and grid-columnconfigure functions. Its most
common use is to set the weight of a column between 0 and 1 to control the
resizing behaviour.
