I wanted a grid like control in HTML (a table with column headers that is
of fixed size but is scrollable).

I tried putting a table header, then underneath an IFRAME with a table inside
it. However the syntax for IFRAME requires a SRC= parameter which means
the table data I want to display has to be in a separate file.

I will be generating the data on the fly. Is there a way to specify the
table data inline instead of having to have a 2nd HTML/ASP?

Or are there better ways of implementing a grid?
