So far, this is the best implementation that I have come across for a scrollable table.

Is there a way to modify this script so that you can also have a locked left column in addition to a locked row at the top?

Thank you.

How can I use rowspan.

codemiles

rowspan control the number of span rows in your table . You can have one column that have length of two rows , or three ,
you use it with <Td> tag :

Code:

I have since found another script, by Richard Cornford, that allows for a locked top row, and a locked left column:

http://www.oasections.com/articles/scrollabletable.html

also, rowspan and colspan can be used as normal

Scrollable HTML table JavaScript code can be used to convert tables in ordinary HTML into scrollable ones. No additional coding is necessary. All you need to do is put header rows (if you need them) in THEAD section, table body rows in TBODY section, footer rows (if you need them) in TFOOT section and give your table an ID field, include the webtoolkit.scrollabletable.js file and create ScrollableTable() object after each table.

Scrollable HTML table code tested in IE5.0+, FF1.5+.
