Customize new Footer

[kdkavanagh]

What's the best way to append additional widgets to the new footer? For example, I'd like to add a (right-aligned) current selected row number of a datatable to the footer. I've tried extending the Footer class as below, but this ends up missing all the default bindings.

class TableFooter(Footer):

    def compose(self):
        yield from super().compose()
        yield FooterRowCount()

Looks like I just needed to adjust the grid CSS to account for my new column(s), since the Footer class explicitly sets the number of columns to the number of displayed bindings

class TableFooter(Footer):

    def compose(self):
        yield from super().compose()
        yield FooterRowCount()
        self.styles.grid_size_columns = self.styles.grid_size_columns + 1
