Use the bind method to bind the table to a field with records, and the table columns to the record's fields. When you set a different data source, the table will automatically bind to corresponding records. For example:
We provide the bind API to solve complicated call issue; you can use it as shown in the below code:
Example 1:
Example 2:
When you have already bound the data source, you can get the dirty table rows if you change the data source value:
