e924. allowing the user to move a column in a jtable component.txt

这里面包含了一百多个JAVA源文件

By default, a table allows the user to reorder its columns. This example demonstrates how to disable this feature. 
    int rows = 3;
    int cols = 3;
    JTable table = new JTable(rows, cols);
    
    table.getTableHeader().setReorderingAllowed(false);
    
    // Programmatically moving a column is still possible
    table.moveColumn(table.getColumnCount()-1, 0);
    // the last column is moved to the first position
