title: Applying row height to all rows including and after row 7
body: <p>I cannot figure out how to apply a row height on an existing worksheet unless I do it one row at a time.</p>
  
  <p>This works for a single row:</p>
  
  <pre><code>ws4.row_dimensions[14].height = 25
  </code></pre>
  
  <p>But I want to set the row height for row 7 and any subsequent rows. </p>
  
  <p>This approach does nothing yet does not throw an error:</p>
  
  <pre><code>for rows in ws4.iter_rows(min_row=7, max_row=None):
      ws4.row_dimensions.height = 25
  wb4.save('C:\\folder\\DataplusRows.xlsx')
  </code></pre>
  
  <p>Any idea how to do this? I can't glean the answer from the openpyxl documentation. And I can't seem to find examples anywhere.</p>
