jquery - jquery UIタブでjQGridのページネーションが機能しない

Question

私はjQueryグリッドを使用しており、クエリUiにはタブ内にグリッドがあります。私の問題は、最初にページングが機能せず、フィールドの並べ替えをクリックしてからページネーションのみが機能することです

var data = [[48803, "DSK1", "", "02200220", "OPEN"], [48769, "APPR", "", "77733337", "ENTERED"],[48803, "DSK1", "", "02200220", "OPEN"],[48803, "DSK1", "", "02200220", "OPEN"],[48803, "DSK1", "", "02200220", "OPEN"],[48803, "DSK1", "", "02200220", "OPEN"],[48803, "DSK1", "", "02200220", "OPEN"],[48803, "DSK1", "", "02200220", "OPEN"],[48803, "DSK1", "", "02200220", "OPEN"],[48803, "DSK1", "", "02200220", "OPEN"],[48803, "DSK1", "", "02200220", "OPEN"],[48803, "DSK1", "", "02200220", "OPEN"],[48803, "DSK1", "", "02200220", "OPEN"],[48803, "DSK1", "", "02200220", "OPEN"]];

    var names = ["id", "thingy", "blank", "number", "status"];
    var mydata = [];



    $(function() {

        var $tabs = $( "#tabs" ).tabs({
             show : function(event, ui) {
                 var mydata = [
