title: What does "index" stands for in TableRow.addView (View child, int index)?
body: <p>Is it meaning that you can build a table row with an empty column ?</p>
  
  <p>I want to do a TableLayout like this :</p>
  
  <pre><code>+--------------+---------------------+
  +  *Nothing*   +     LinearLayout    +
  +------------------------------------+
  + LinearLayout +      *Nothing*      +
  +--------------+---------------------+
  </code></pre>
  
  <p>Is it possible with index property ?</p>
  
  <pre><code>TableRow topTableRow = new TableRow(context);
  topTableRow.addView(xAxisScrollView, 1);
  addView(topTableRow);
  
  TableRow bottomTableRow = new TableRow(context);
  bottomTableRow.addView(yAxisScrollView, 0);
  addView(bottomTableRow);
  </code></pre>
