            {

                p_w_picpath.PicAddress = "http://localhost:8088/pic/Image/" + p_w_picpath.PicAddress;

            }

            dataIndex: 'Id',

            width: 100,

            menuDisabled: true,

            sortable: true,

            renderer: function (value, metaData, record, rowIndex, columnIndex, store) {

                var url = 'http://localhost:8088/Image/';

                var fileName = store.getAt(rowIndex).get('PictureName');

                var img = "<img src='" + url + fileName + "' width='300' height='200'>";

                metaData.tdAttr = 'data-qtip="' + img + '"';

                return value;

            }
