Yep, that'll do it.  As un-Pythonic as it seems, you need to do
something like this:

    headerTableData = [[''] * cols for j in range(rows)]

That creates a new list every time

    >>> y = [['']*cols]*rows
    >>> z = [[''] * cols for j in range(rows)]
    >>> y
    [['', ''], ['', ''], ['', '']]
    >>> z
    [['', ''], ['', ''], ['', '']]
    >>> y[0][1] = '9'
    >>> y
    [['', '9'], ['', '9'], ['', '9']]
    >>> z[0][1] = '9'
    >>> z
    [['', '9'], ['', ''], ['', '']]
    >>>.
