That's easy for columns.....
Rows I am not sure about. Here is the code I used

   // hides the column with model index 'col'
    protected void hideColumn( int col )
    {
        for( int j = 0; j < tcm.getColumnCount(); j++ )
        {
            if( tcm.getColumn(j).getModelIndex() == col )
            {           
                tcm.removeColumn( tcm.getColumn( j ) );
                break;
            }
        }
    }
    // Displays a column
    protected void viewColumn( int col )
    {
        tcm.addColumn( tCols[col] );
    }
