Adding rows to a block?

Hi again,

Kinda feeling a little stupid here, but working through how layout is handled in Blocks

I was adding a gallery page for videos. The default page has 3 rows, 1 header row and 2 rows with 4 videos per row.

Is there a way to add additional rows to this block without adding additional blocks to the page?

its no possible

Select a row and duplicate it. Duplicate can be found in the main menu along the top of the screen and in the rows contextual menu.

it is a separate row, how to create it on one table?

And please say how to move to the top the row?

i can’t doit in classes.
