title: hide column (header and rows) post jqGrid render
body: <p>Is it possible to hide a specific column in jqGrid after it has been setup, while ensuring all alignments are correct (table width and header/data alignment) for IE/FF.</p>
  
  <p>The data can't be removed at back-end w/o major refactoring.</p>
  
  <p>I am reiterating through a specific column and checking if it is all empty, and if so, I tried .remove() on the header and cells for that column, but the alignment goes off seriously (I think setGridWidth is still taking into account that removed column's width). I know there is a hide option when jqGrid initialises... but not sure if there is a method for that post render.</p>
