how to shutdown and open the table sorting function on a jquery sorter table?

Question

After shuting down the table sorting function on a jquery sorter table by using: $("#table_"+appId).tablesorter({ headers:{ 0:{sorter:false},1:{sorter:false},2:{sorter:false}, 3:{sorter:false},4:{sorter:false},5:{sorter:false}, 6:{sorter:false},7:{sorter:false},8:{sorter:false} } }); I want to re-open the sorting function when some events triggers. How can I do that? I have tried several methods, like: 1. re-initialize it, $("#table_"+appId).tablesorter({widgets: ['zebra']}); 2. use: $("#table_"+appId).tablesorter({ headers:{ 0:{sorter:false},1:{sorter:false},2:{sorter:false}, 3:{sorter:false},4:{sorter:false},5:{sorter:false}, 6:{sorter:false},7:{sorter:false},8:{sorter:false} } }); But they are all useless. Hope anyone can help me on this issue.
