Unable to tab through the header elements before the body of the table

Hey,

I'm having an issue trying to use TAB to each access the header of the table before the the body. I believe this is caused by the way the table is rendered. In the image, the element for the body of the table with classname "BaseTable_body" is rendered before the header element with classname "BaseTable_header". Is there a work around so the header is rendered above the body of the table so we can use the TAB key to access the header cells before the body of the table?
