It does sound to me like your problem is exactly the same as mine in that blog. I'm copying a table from a transaction (in my case a custom transaction, but that's not relevant here) to SMEN.
The problem is just that there is no way to add a table to SMEN. There's no custom table object in the editor, and while there is a "Copy Table" action, there's no "Paste Table" action.. That's why in my blog I add a load of individual text fields that just "look" like a table. And that's why all the JavaScript is needed to manage the scrolling.
Does that make sense?
