您可以在 .load() 回调，如下所示:

You can run the code again in the .load() callback, like this:

$("#"+content_show).load('new-page.php', function() {
  $("#sorttable").tablesorter({
    headers: {0: {sorter: false}}
  });
});

加载内容后，它将再次执行.tablesorter()插件.

This will execute the .tablesorter() plugin again once the content is loaded.
