sorting content of table at client side

P: n/a
Hello,

Fiest of all let me thank this group for so quick in responding to any
postings.
I am using a javascript based utility from a site to sort the columns
of the table. But, for some strange reason it is not working on colmuns
containg checkboxes, text-boxes (or, any user input fileds). For
checkbox column, the values are lost when clicked on the column title
to sort.
I tried a lot to modify but couldnt achive what I wanted.

I have pasted the code of 'SortTable.js' and the HTML file
'SimpleSample.html'

Please help me out.

Thanks a ton,
CG

Good luck.
