 # Controlled sorter
 
 If one of the column objects' `sortOrder` is set to `'ascend'`, `'descend'` or `false`. The sorting behavior the table will be in a controlled manner. If multiple columns' `sortOrder` are set to `'ascend'` or `'descend'`, only first column of them will be applied.

 # 受控的排序
 
 如果列对象的 `sortOrder` 属性被设为 `'ascend'`、`'descend'` 或者 `false`，表格的排序将为受控状态。如果很多列的 `sortOrder` 都被设定了，那么只有他们之中的第一列会生效。
