Creating Column Headings
It is
possible to create a
GridLayout
that mimics a table for
presentation of data. When this is the design effect you wish to
achieve, you must create column headings in the first row of the
grid. Text
widgets are then used to fill out the
additional rows in the table.
How do I do that?
Example 9-5 demonstrates how
GridLayout
can be used to create a table for
presentation of data in text fields aligned in a grid.
