Dynamic height for lines

Hi All,

Below is my form layout -

The middle boxes are always blank and just need to show as columns. Now, there is a chance of more data on both Black circle data and red circle data.

If any of these increased, then I want to show the blank cells as well with vertical lines (separating columns). I tried subforms etc., but no luck, any help is highly appreciated.

Required format:

In below : right side second red box has multiple values as i told, so I need to have lines like green color dynamic increased.

Thanks,
Chandra.
