> extendedDataTable header renders OK if entire table or panel that contains it are rendered.  if I render just the header row using render="table at header" format, the header row re-renders, but its format is lost (refer to the attached screenshots). Checkbox in column 1 is the trigger for this issue.  
> * Header contains 'select all' checkbox, each data row contains row-level checkbox.  
> * Click on data row will rerender the header row and this is event that causes alignment to go off.  
> * If I rerender the entire table and/or panel, this does not happen, but causes undesirable performance problems when clicking individual rows in succession due to delays from jsf 2 / richfaces 4 render cycles.
> It looks like the header-only render is trying to do a vertical center of header cell contents while the panel/table render is not, causing the cell contents to slide down vertically in the header cell.
> This problem occurs in every browser I tested: IE 9, Firefox 16, Firefox 17, and Chrome 23.0
