title: How to set the column text format of QTableWidget?
body: <p>I want to show some data in table form. I took <code>QTableWidget</code> for it having multiple columns. One column of it will contain <em>time(hh:mm format)</em>.</p>
  
  <p>I also want user to edit any item of table but with corresponding format.</p>
  
  <p>I was able to add data in <code>QTableWidget</code> but i couldn't set text format of <em>time</em> column.</p>
  
  <p>This i want to achieve so that user can edit time only in <em>hh:mm</em> format.  </p>
