You need the row / column containing the header cells in the same data table. 
See http://www.w3.org/TR/REC-html40/struct/tables.html#adef-headers
So it fails SC 1.3.1. In any case the headers row and the first table  is providing structure for the content that follows and is not mere "presentation".
For large tables, implement pagination links ... show next 20 or whatever.

A team I am working with is using a technique I am unsure about to mark up their data tables. They have their table split into 2 tables in the HTML markup, one for the header row (which has been marked with role=presentation) and one for the data content. They claim they need to do this in order to obtain the visual layout they require.

The header cells in the first table have ids associated with them which are then being referenced from the headers attribute of cells in the second table.

I can't see any reference in H43 that the cells referenced as a header must be in the same table so it would seem that this would pass 1.3.1 due to meeting H43. Is my interpretation of this correct? If this shouldn't pass H43 I would appreciate the technique being clarified such that this is made more clear.
