title: Setting number of columns programmatically in TableLayout
body: <p>I have an XML layout which contains a TableLayout with an unknown number of TableRows...
  The number of Rows will be established durin runtime, what I do know though is that I want two columns...
  So I have a couple of questions regarding this :</p>
  
  <ul>- is there a way to set the whole TableLayout to have 2 columns ?</ul>
  
  <p>- is there a way programmatically to give an id to the (during runtime) created TableRows which will be placed within the TableLayout, so I can reference them later on from other parts of the software ?
