How to form a table with sizes and colors correctly?

Question

1C-Bitrix

Hello. I need to form a color-size table for a product card from trade offers. What happened is shown in the picture.

The client wants to make it so that if the TP has the same color, it is displayed alone, and the fields for the amount are respectively on the same line. Has anyone done something similar?

Here's what happened


, here's how to do it

It looks like you have a wrong cycle.
you first got a grid of sizes, here I probably would have gone the same way,
and then mark a line for each TP.
you also need to form an array like
'colored'=>[44,46,48,50]
'not colored'=[your size]
and fill in the table using it
