Additional Columns in Table

Content

Hello - I have 2 questions. Second question is design related.

Question 1 - My understanding is if you have a table and want to massage ( manipulate ) data on client side then you use ADP and not SDP. Is that correct ? Also, do we use ADP only if the widget is table or ADP has more applications apart from just backing the table.

Question 2 - we have BO that has 7 fields. This BO is getting  populated from third party application called XYZ.  These fields show up in the table as columns. But same table we want to add 3 more columns ( These 3 columns are Select One LOV ). Data being fed to these LOV drop down is coming from a ERP REST service. In short, this table will have total 10 columns.
