jqGrid表在Mozilla Firefox中不整洁

Question

我创建了一个jqGrid表，它在Chrome中看起来与预期一样，但在Mozilla Firefox中是不整洁的。请参阅下面的屏幕截图和代码。在Firefox中重新加载或排序后，它正确呈现。有谁知道如何纠正Firefox中的初始渲染？

jQuery(document).ready(function(){
  $('#tbl_name').jqGrid('autoWidthColumns').jqGrid({
    url:'GRID/grid_manageProvinsi_data.php?type=provinsi',
    datatype: 'json',
    colNames:['Action','Provinsi','Harga (Untuk Pengiriman Barang)','Terakhir di Update','Updater'],
    colModel:[
        {name:'action',index:'action', width:30, align:'center', sortable:false, search:false, searchoptions:{sopt:['eq','cn']}},
        {name:'nama_prov',index:'nama_prov', width:80, align:'left', sortable:true, search:true, searchoptions:{sopt:['eq','cn']}},
        {name:'harga',index:'harga', width:80, align:'center', sortable:true, search:true, searchoptions:{sopt:['eq','cn']}},

    ],
    pager: '#tbl_name_pager',
    rowNum: 30,
    rowList: [10, 20, 30],
    sortname: 'nama_prov',
    sortorder: 'asc',
    viewrecords: true,
    gridview: true,
    caption: 'Manage Provinsi',
    width: $(window).width() - 275,
    height: $(window).height() - 230,
    rownumbers: true,  
    loadComplete: function () {
        $(this).find('>tbody>tr.jqgrow:odd').addClass('myAltRowClassEven');
        $(this).find('>tbody>tr.jqgrow:even').addClass('myAltRowClassOdd');
    }

  });
  jQuery('#tbl_name').jqGrid('navGrid','#tbl_name_pager',{edit:false,add:false,del:false},
                                {}, // edit options
                                {}, // add options
                                {}, //del options
                                {multipleSearch:true,width:400});

});
