I need to modify the structure of the HTML rendered by the XsltListViewWebPart in the default AllItems.aspx SharePoint page. Specifically, I need to separate the column headings into its own table and the data cells into its own table.
I have customized an Empty Data View web part before and it was very simple since the structure of the table was in the code of the page. For the XsltListViewWebPart the table structure seems to be hidden somewhere else.
How can I change the table structure of this XLWP?
