title: Spotfire: Count number of marked rows, with IronPython, without iterating
body: <p>I would like to know if there is a way to count the number of marked rows of a table in Spotfire, without iterating over all rows of this table, using IronPython.</p>
  
  <p>I am asking this question because this number of marked rows is already available in the little toolbar at the bottom of the software's window. I search on the Internet and in the Spotfire API but I didn't found anything.</p>
