title: Enable-Disable cells of single column in Ext.grid.EditorGridPanel
body: <p>I have <strong>EditorGridPanel</strong> and I want Enable-disable cell values depending on other column value of same Row and I am using <strong>Extjs 3</strong>. As I tried to find out a solution on Google there is I found that
  I can able to use <strong>RowEditing plugin</strong>. I don't want to use this plugin, so is there another way to do this?</p>
  
  <p>And I want to do this enable and disable when click on Edit button, so I can able to do this on <strong>"beforeedit"</strong> event. 
  here I am getting issue that how I can able to access one particular cell object and how I can able to enable and disable that cell object. There is method to enable-disable whole column of
  grid but is there any method which returns that particular cell object and enable-disable this cell object?</p>
  
  <p>Is anyone knows is there any way to do this, please let me know. Thanks.</p>
