Disabling and Enabling the table control lines

Hi all,

Iam having the scenario where in whenever we fetch the data into a table control from another tablecontrol or internal table, the lines of data occupied by target tablecontrol should be in disabled mode ( i.e, output only mode).

Whenever user enters data manually in the lines of table control, those lines should be in the enabled mode ( so that those can be editable further).

Approach :

Initially I made the table control fields as output only. Whenever enduser clicks a pushbutton, iam adding two more lines to the table control for manual entry.

But it is not working. Whenever enduser clicks button it should add two lines and these lines should be in the enabled mode. Please give me some idea of how to set the added lines in enabled mode programmatically.

Thanks in advance
