Accessible WRIA components

I'm researching for "best practices" for a WRIA data table component that contains the following elements:
- Hierarchical table that allows users to expand/collapse the vertical hierarchy.
- Data tables with more cols than fit nicely within a web page.  Many users have been asking for a feature where they can traverse the table horizontally without losing the ability to see the first column of data.  (This is akin to Freeze Pane feature in Excel.)
- Ability to let users hide/show table columns on the fly.

Can anyone point me to a good resource for information on developing accessible WRIA components?  Most particularly, I'm interested in WRIA components that would support the above table implementation.
