Pressing Enter On Table control

Hi Friends

I am having a problem with a table control.

I want to use a table control for user input.

I have painted a screen and placed a table control on it.

When i execute the program this screen appears first.Now when i enter some data in the table control and press "ENTER" button(of keyboard) then the data in the table control disappears.

I wants that that after pressing ENTER the data should display(remain) in table control unless until i dont press any submit button of my screen.

(I have created table control with reference to an internal table and all the fields are of input output type.)
