I have created a tabulator table and it looks great exactly what I want...

I am then giving the users the ability to save it. I am saving the data, and the column definitions.
When I bring it back I the formatting looks completely incorrect, see below.
So the columns are there and look correct. The data is there, but clearly, the formatting is wrong. Can anyone suggest what I am missing to ensure the table comes back as expectetd??
Thanks
