title: Hide text in column as password dots in QtTableWidget
body: <p>I have table (created by QTableWidget).</p>
  
  <p>My table has 3 columns</p>
  
  <pre><code># | user | pass
  </code></pre>
  
  <p>Text in user and in password is visible i.e "user", "password"</p>
  
  <p>I want to hide text in pass like:</p>
  
  <pre><code>"********" &lt; means "password"
  </code></pre>
  
  <p>In QLineEdit is good option called "echomode" but it is only for QLineEdit.</p>
  
  <p>I can manually replace text for *, but how can i read this text later from a table (in class) ?</p>
  
  <p>Better than ** will be dots. (like echomode -> password)</p>
  
  <p>Regards</p>
