This is a rectangular array of `Label` instances: as such it is a passive
widget. Rows are of a fixed height equal to the font height + 4 (i.e. the label
height). Column widths are specified in pixels with the columen width being the
height). Column widths are specified in pixels with the column width being the
specified width +4 to allow for borders. The dimensions of the widget including
borders are thus:
height = no. of rows * (font height + 4)
width = sum(colun width + 4)
width = sum(column width + 4)
Cells may be addressed as a 1-dimensional list or by a `[row, col]` 2-list or
2-tuple.
Constructor args:
writer, row, col, lwidth, nrows, ncols, invert=False, fgcolor=None, bgcolor=BLACK, bdcolor=None, justify=0
