Grid gap setting

where is the proper place to set a grid-gap,grid-column-gap and grid-row-gap for a common grid control?

I tried set in CSS and Grid1 itself, but did not affected

Please advice

Thanks

The best place to set this is in ProjectCSS, in the Project menu.

This sets the padding for all elements in Grid1.

#Grid1 td {padding:10px;)

The Common Grid is based on the HTML Table element.
