For list boxes, a table that can be linked with the current form table is indicated. The link table must have at least one field in common with the table of the current form. This makes it possible to establish an unambiguous reference.
对于列表框，此处将显示可与当前表单表格相链接的表格。链接表格必须至少有一个字段与当前表单表格的字段相同。只有这样，才能建立明确的引用。
