Reduce the spacing pls.?

Hello

I placed a table format on my_form, but, as users want to have just a white box (I mean, with out lines) hence I deactivated the lines/roes, hence now it look like a white box, well

But, the SPACING between the lines more (pls. see the red vertical line in the below pic), we want to have les spacing between 2 lines, pls. let me know how can I achieve it?

Below are my settings,
