title: iTextSharp set default font-size
body: <p>I am using iTextSharp to create a new pdf-file.
  The pdf will contain one headline and one pdf-table.
  The file-size of the resultant pdf-file should be as small as possible, so I use the default font (Helvetica, 12pt). 
  Is there a way to change the default-font-size from 12pt to 8pt.</p>
  
  <p>I know that I can set the font for each pdf-table-cell.</p>
  
  <p>But is it possible to set the default-font-size for the whole document/table, so that I don't need to set the font for each and every table-cell extra?</p>
  
  <p>(I googled on this topic, but did not find an answer)</p>
