How to move columns around in Web ADI template?

Hi everyone,

We are on 11.5.10 and the question is about GL journals.  There are two problems:

1) Anytime when I unprotected the sheet and inserted a blank column, all the names in headers area (category, period_name etc) were gone.  When I uploaded the journal, system apparently knew what is what and put them back.  So I just wonder how to insert a column and still keep the names in headers?

2) Default order in journal references is 1,4,2,3,5 and it is prefered to move 4 to the position between 3 and 5, like 1,2,3,4,5.  When I did that and upload, the positions are wrong and system gave me 1,3,4,2,5.  Moving columns worked in Desktop ADI but not in Web ADI.  So what is the correct way to reposition a column in Web ADI in 11.5.10?
