title: Resizing QTableWidget Columns and Rows to Fill Table
body: <p>I have a QTableWidget with an N number of columns, which when the number of columns are set, they automically fill in the entire QTableWidget. When I try to dynamically change the number of columns to N/2 columns, the size of each column does not change. This results in the right half the QTableWidget being nothing but whitespace.</p>
  
  <p>Conversly, if I were it reset the column count to 2*N, the column widths adjust themselves appropriately and fill the QTableWidget.</p>
  
  <p>I'm wondering how I can reset the number of columns and row without the QTableWidget having any whitespace?</p>
