title: Excel Export: Text Objects in title band or groupheader band get their own separate columns
body: <p>I need to have QuickReport export to XLS files,
  The problem is that I get empty columns in between my data objects,
  That happens because while the stream is being created, columns are set
  according to the objects position from top to bottom, in such a way that
  if an objects left position is not set to the exact same position
  as a detail objects left underneath it, that object will get
  its own separate column, which will then result in empty cells underneath it
  which can otherwise be occupied by detail objects.</p>
  
  <p>An example would be: if the title was "Customer List" and the two detail columns
  were "Customer Nr" and "Customer Name", the title would be placed in say B1,
  then the two detail objects would receive A2 and C2. What I want though is
  to for them to receive A2 and B2:</p>
  
  <pre><code>~~~~~~~~~|Customer List|~~~~~~~~~~~
  
  CustNr~~~|(Empty Cell)~~|~CustName~~ -&gt;Not good (This is what I'm getting now) :(
  
  ~~~~~~~~~|Customer List|~~~~~~~~~~~~~
  
  CustNr~~~~|CustName~~|~~(empty Cell)} -&gt;Good (This is the wanted result) :)
  </code></pre>
  
  <p>I was thinking theoretically, what needs to be done is to not have the
  head band taken into consideration when determining the max number of columns,
  but I have no idea how to achieve that.</p>
