Smartform- ouput table,main window

Hi

Can anyone please help with my two questions?

I have a main window, in which there is a dynamic table.

My problem is the content of table will spread to next serveral page if the height of main window set too short or the main window is too big there are too much empty place left.Can anyone please tell me how to make the size of main window determinded by the lenght of the table.

The other question is although I have shaded my table in the table painter but the shading doesn't appear when display the form.

Thanks

Heather
