getting 100.0% as sum of a column percentages in expss package

Hi,
I have been trying to generate a table through expss package by using the following code:
df |>
tab_cells(ssskill_rel) |>
tab_cols() |>
tab_stat_cases(label = "N") |>
tab_stat_cpct(total_row_position = "none", label = "Col %") |>
tab_pivot(stat_position = "inside_columns") |>
tab_caption("Relevance of skills for software tools")

and following is the output:

My question is: how to get sum of column percentages (100.0%) in the total cells?
