title: free-jqGrid Filter toolbar shunt subgrid column width plus
body: <p>I'm using free-jqGrid 4.13.3.
  I composed a grid with filter toolbar and this grid has subgrids elements such in this screenshot :
  <a href="https://i.stack.imgur.com/UkHB5.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/UkHB5.png" alt="enter image description here"></a>
  The subgrid column (which contains plus and minus signs) appears in filter toolbar, this has been ripped on left and make last column without filter, as it is on his left, under the dog icon.</p>
  
  <p>So search in "N°" column doesn't match because ripped on left.</p>
  
  <p>Same thing with this other screenshot :

  <p>I hope I am well understood with my explanation.</p>
  
  <p>Please is there somebody who can drive me to correct my mistake ?
  Many thanks in advance</p>
  
  <p>Cheers</p>
