Hi Javier,

if I understand it correctly, you want to rename the headings of the
Results Table? I fear that this is not possible via the macro language.
It would be doable in javaScript:

   rt=ResultsTable.getResultsTable();
   rt.setHeading(1, "Bleach");
   rt.show("Results");


What you could do in the Macro Language is creating your own macro to
save the Results Table, e.g. using File.saveString(string, path).
You could first write the headings of your choice to the String, '\n',
and then read the Results Table line by line, and add its elements to
the String, with tabs ('\t') and linefeeds ('\n').
Not very elegant, however.

Michael
