1.添加js到页面

$.extend($.fn.datagrid.methods,{    columnMoving: function(jq){        return jq.each(function(){            var target = this;            var cells = $(this).datagrid('getPanel').find('div.datagrid-header td[field]');            cells.draggable({                revert:true,                cursor:'pointer',                edge:5,                proxy:function(source){                    var p = $('
    
').appendTo('body');                    p.html($(source).text());                    p.hide();                    return p;                },                onBeforeDrag:function(e){                    e.data.startLeft = $(this).offset().left;                    e.data.startTop = $(this).offset().top;                },                onStartDrag: function(){                    $(this).draggable('proxy').css({                        left:-10000,                        top:-10000                    });                },                onDrag:function(e){                    $(this).draggable('proxy').show().css({                        left:e.pageX+15,                        top:e.pageY+15                    });                    return false;                }            }).droppable({                accept:'td[field]',                onDragOver:function(e,source){                    $(source).draggable('proxy').removeClass('tree-dnd-no').addClass('tree-dnd-yes');                    $(this).css('border-left','1px solid #ff0000');                },                onDragLeave:function(e,source){                    $(source).draggable('proxy').removeClass('tree-dnd-yes').addClass('tree-dnd-no');                    $(this).css('border-left',0);                },                onDrop:function(e,source){                    $(this).css('border-left',0);                    var fromField = $(source).attr('field');                    var toField = $(this).attr('field');                    setTimeout(function(){                        swapField(fromField,toField);                        $(target).datagrid();                        $(target).datagrid('columnMoving');                    },0);                }            });            // swap Field to another location            function swapField(from,to){                var columns = $(target).datagrid('options').columns;                var cc = columns[0];                _swap(from,to);                function _swap(fromfiled,tofiled){                    var fromtemp;                    var totemp;                    var fromindex = 0;                    var toindex = 0;                    for(var i=0; i

2.在对应的datagrid实例化之后，添加本功能。

$('#id').datagrid("columnMoving");
