must be this function:

as you see it just counts the cells in the first row of the table, and
calls that the number of columns...

whether that is correct or not is arguable: in core Writer tables, there
are actually no columns; there are just rows, and each rows contains
some number of cells, and there's no requirement that there must be the
same number of cells in each row; the columns in the API wrappers then
somehow badly try to emulate columns on top of the core rows-and-cells
data structure...
