How do I change column widths in a .net datagrid

I am creating a .net form which uses a datagrid.  The datagrid uses a datatable to get its data from.  There are 5 columns in the datatable and I want to individual size each of the column widths based upon maximum data size.  I would also like to be able to wordwrap the column headings so that the column heading can be more descriptive of the data in the columns.
