0.17.3 MathTable - first and last column of MathTable are truncated

Description of bug / unexpected behavior

Setting a fixed width of the columns in a MathTable() is not correctly supported for the first and last column, which are truncated at the left and right edge of the table elements.

Expected behavior

The given width should be obeyed independent on the contents of the cells.

How to reproduce the issue

class Test(Scene):
    def construct(self):
        mytable = MathTable(
            [[1, 10, 100, 1000, 10000, 100000], [0,0,0,0,0,0]],
            h_buff=.1,
            v_buff=.1,
            include_outer_lines=True,
            arrange_in_grid_config={"col_widths":[3]*6, "col_alignments": ["c"]*6}
        ).scale_to_fit_width(10)
        self.add(mytable)
