Mutliple Header Rows.

[christianallred]

Its not currently possible to put two rows in a

<Thead />

Well I have also a need to put a customized row above the filter header row.

Also they have to have colspan attributes. I will try to customize it the next days. But would be cool, if there is a small tip for this issue :-D

Github's issue search saves the day, I was about to submit a duplicate issue! Here's what I was going to post:

This is somewhat related to Support colspan and rowspan #84 but not.

I have a table I need to render that has multiple sets of columns that are related. I want 2 rows in the Thead, the top one would have Th elements with colSpan that would be a description of the columns below it. Basically I'm trying to achieve something like this:

Name	Group 1			Group 2			Group 3
	Col 1	Col 2	Col 3	Col 1	Col 2	Col 3	Col 1	Col 2	Col 3

In my case, the "Group 1", "Group 2", "Group 3" cells I'd want pretty much ignored by reatable (not sortable, not filterable, etc.) The "Col 1", "Col 2", "Col 3" cells are what I'd need reactable to interact with.

I'm sure it's a big ask, but wanted to throw it out there.
