select colname, count(*) from datatable ..... help

[SidTheSquid]

Hi, I have a myDataSet that has a dataTable tableSource. Its data from a web traffic log broken up in their repective columns.

I would like to create a vb.net function that takes in paramenters [columnName as string, tableSource as dataTable]
and returns a dataTable (or view). Its functionality would be equivalent to

"select columnName, count(*) from tableSource group by columnName"

In the end, I would like something like

ColumnName Count
IE6 345
IE5 35
Netscape 765
etc

I have no clue how to do this using dataview's filter, so any help you can give is super appreciated.
Thanks
Sid.
