Select "title" in the table, and in the property grid change "NullValue" to "(empty)" - that is, treat the title as the empty string whenever no data exists for it, instead of throwing an exception.

在Datatable中选中“title”，在属性栏里将“NullValue”的值更改为“(Empty)”-这样做是为了在没有与“title”对应的数据时，把title做为一个空字符串来对待，以此替换抛出异常。
