There is currently no way to work with a Results table in a headless macro. The macro will attempt to display the table, which will throw an exception. The work around is use a scripting language, as in the following JavaScript example, which opens a table (without displaying it), prints a summary of the table and lists all the “Area” values.
rt = ResultsTable.open(filePath);
print(rt);
for (i=0; i<rt.size(); i++)
print(i+" "+rt.getValue("Area",i));
