Hi,

headers and cells should be associated via the id and headers attributes
mechanism (even better if you can simplify your table and not have
colspan and rowspan. If).
WCAG Techniques H43 and F90 are relevant here:

* H43: Using id and headers attributes to associate data cells with
header cells in data tables
<https://www.w3.org/WAI/GL/WCAG20-TECHS/H43.html>
* F90: Failure of Success Criterion 1.3.1 for incorrectly associating
table headers and content via the headers and id attributes <F90:
Failure of Success Criterion 1.3.1 for incorrectly associating table
headers and content via the headers and id attributes>

This bookmarklet by Gez Lemon may help verifying the tedious – and prone
to error –  work of adding headers:

> I'm trying to figure out how to make a table read the headers properly when a data cell spans multiple columns. We have a data table (gist URL below) where we're describing fines for library resources, and some of the fines are the same across multiple groups, so naturally we used "colspan" to make it clear that the information pertains to multiple groups. Unfortunately, when I tested this out with NVDA, it only read the first pertinent header for the data. I'm not sure why this is happening, as the markup looks correct to me.
