Tables are not that complicated
There isn't a lot about tables that is not already well known. For accessibility you might want to be careful of a few things.
<caption> element should be added to all your tables as sort of title for this table. It will inform all users what the table is about:
<caption>I'm a table title!</caption>. Use the
scope="col" on your
<th> columns to explain to screen readers that the element is a the start of the column and
scope="row" for the same
<th> elements that start rows.
If you need to make more complicated tables accessible, try take examples in the MDN documentation on this page.
