Have a look at this thread: http://communities.ptc.com/thread/35930
You could use the parameter to eliminate rows from a table where a value matches the value of a parameter using a filter.
I think you cannot use a parameter value as a way to select other parameters in the table. That is, if you have a parameter "Width" and another "Depth" you cannot have a parameter "Select" that can be used to define a column that switches between the other two.
