Feature request: add section_div to summarize_row_groups()

[wwojciech]

Add section_div parameter to summarize_row_groups() function.

I think it is enough if you add it to the previous split the summarize is based on.

If you need it to be more versatile (like adding spaces just after the table etc) you can use section_div(tbl) <- " " with the right modifications

Thank you @Melkiades . This feature request was requested by @gmbecker after we had a conversation about it.

Hi @Melkiades,

The issue is that we want to declare a divider between the content rows and the rows of the table being rendered, ie after the group summary.

Setting section_div in the split_rows_by doesn't do this, it only sets them after each block (which includes both the content rows and the subtable rendering). Thats why we were asking for there to be a way to do it in summarize_row_groups
