function hyperlink doesn't resolve column

```
What steps will reproduce the problem?
1. Try to get a hyperlink and ask for column "a". You will receive an error
that the index doesn't exists.

Issue is that the hyperlink function should resolve the column as well or
performs some additional check if it's a resolved column or a clear column.

Documentation doesn't reflect.

Solution is to add the following to line #384:

$col = $this->getCol($col);

.. and it will work. The (raw) and (type) functions have probably the same
issue.

Here is an easy fix how to make it even better:

$col = is_numeric($col)?$col:$this->getCol($col);

Which is a dual approach. Now the programmer can either give a numeric value or
a named value.

Hope that helps!

Thanks,

Andy

Start at line 384 in the hyperlink function and inspect how the column argument is handled. Update the column handling so named and numeric columns work, then verify that hyperlink, raw, and type calls no longer reject a resolved column.
