I contacted cs-cart on this issue and this is their response. Not sure that this an answer. Can't they just make the take adjustable> Frustrating!
It seems, the Name / CODE column becomes smaller, because of the additional eBay and Amazon columns and the thumbnails width.
I can recommend you to change the thumbnails width to the default 50 value to slightly increase the width of the Name / CODE column. You can change this in admin panel on page Settings > Thumbnails in the Admin panel: product mini-icon thumbnail width field.
If this solution does not suit you, an additional code modification is required to change the width of the Name / CODE column. Such modification is estimated at 10-20 support credits. Please let me know, if you are interested in it.
