Hi Kentan
according to your description, I guess there is one important step left. First, the table needs to be set as "simple-2-d region" which you can find by "table-repeat region-add-simple", just do as insruction in your drawing, and then click the table where you want to add your own parameter, say ,sequence-"rpt.index" and so on, then set the simple-2-d region's attribute as your requirement, and finally update the table, you will get the result.
wish this would help you.
