Hiding a row (or column) in the model is "simply" a matter of removeRows() and 
removeColumns(). The model is only a representation of the data to show. So 
there is no hiding. Only not exposing it via the model.

There is a way to hide stuff without modifying your model: Use a proxy-model on 
top to hide (ie. not expose) your rows/columns. Then all the views attached to 
that proxy will get the filtered data.

Have fun,

Arnold
