jquery tablesorter Dynamic Update table

Recently using jquery Tablesorter, encountered a problem, need to delete the contents of the tbody, re-read from the network, and then load the sorting, Baidu has not found a solution for a long time, no way, only crossing Web documents
Official website Help Address
Looking for a long time finally found the configuration
$("#myTable1 tbody").empty();
$("#myTable1 tbody").append(html);
**$("#myTable1").trigger("updateCache");**
$("#myTable1").trigger("update");
This part of the bold is critical, as the official website says:
Updatecache Update the parsers, only if not defined and then Update the internal cache (v2.15.4).
It updates the data maintained by Tablesorter itself, puts the latest data into the built-in storage, and removes old data
