Custom Ruling & Shading via ExtendScript

Hi,

I've taken up learning ExtendScript to tackle some common problems in my workflow.

My current project is to write a scrip that applies white rules to the columns in table heading rows.

So far my script can select the top (heading) row of the appropriate tables. But I can't figure out what the commands are for applying ruling. I've searched through every piece of documentation I could get my hands on, but there doesn't seem to be extensive material written with the beginner in mind.

Here's the script so far (Note: the counter and the alerts are just there so I know everything is working as I go along):

//target the active document

var doc = app.ActiveDoc;

//target the "first" table

var table = doc.FirstTblInDoc;

//number of tables to edit

var numberOfTables = 0;

if(table.ObjectValid() == true)

{

    while(table.ObjectValid() == true)

    {

        if(table.TblTag == "WithHeading")

        {

            numberOfTables++;

            alert("The table '" + table.TblTag.toString() + "' will be edited.");

            //select the top row of the table

            table.MakeTblSelection(0, 0, 0, table.TblNumRows - 1);

            table = table.NextTblInDoc;

        }

        else

        {

            alert("The table '" + table.TblTag.toString() + "' will not be edited.");

            table = table.NextTblInDoc;

        }

    }

}

else

{

    alert("No more tables.");

}

alert(numberOfTables + " tables will be edited.");
