您可以利用Filter Options部分来选择所要显示的列、分类顺序和指定作为筛选标准的sql语句。

You have the ability to select columns to display, sort order, and specify an SQL statement for filter criteria, using the filter Options section.

因为分类属性可以是多值的也可以是单值的，所以要用try - catch语句检查它。

Because the category property can either be multivalued or single-valued, you check for it with a try-catch statement.
