Adding tables to Stores > Tables using jscript

Is there a way to add tables to Stores > Tables uisng jscript (same way as picture can be added to Stores > Regions using "Regions.AddPicture" method)?

var table = (myProcess).WinFormsObject("dgvTable"); //table has 10 columns

I would like to add only 5 columns of "resultsTable" object using jscript. I know how to add them manually by Right-click > New Item > Highlight the Object > Select required columns. But I have multiple tables that I need to add and would like to do that using script.

Thanks in advance for your help.
