解决方法 页面加上修复JS:
    (function ($) {
            $.extend($.fn.datagrid.defaults.view, {
                insertRow: function (target, index, row) {
                    var state = $.data(target, 'datagrid');
                    var opts = state.options;
                    var dc = state.dc;
                    var data = state.data;
 
                    if (index == undefined || index == null) index = data.rows.length;
                    if (index > data.rows.length) index = data.rows.length;
 
                    for (var i = data.rows.length - 1; i >= index; i--) {
                        var tr2 = opts.finder.getTr(target, i, 'body', 2);
                        tr2.attr('datagrid-row-index', i + 1);
                        tr2.attr('id', state.rowIdPrefix + '-2-' + (i + 1));
                        var tr1 = opts.finder.getTr(target, i, 'body', 1);
                        tr1.attr('datagrid-row-index', i + 1);
                        tr1.attr('id', state.rowIdPrefix + '-1-' + (i + 1));
                        if (opts.rownumbers) {
                            tr1.find('div.datagrid-cell-rownumber').html(i + 2);
                        }
                    }

                    var fields1 = $(target).datagrid('getColumnFields', true);
                    var fields2 = $(target).datagrid('getColumnFields', false);
                    var rowId1 = state.rowIdPrefix + '-1-' + index;

                    if (index >= data.rows.length) {	// append new row
                        if (data.rows.length) {	// not empty
                            opts.finder.getTr(target, '', 'last', 1).after(tr1);
                            opts.finder.getTr(target, '', 'last', 2).after(tr2);
                        } else {
                            dc.body1.html('<table cellspacing="0" cellpadding="0" border="0"><tbody>' + tr1 + '</tbody></table>');
                            dc.body2.html('<table cellspacing="0" cellpadding="0" border="0"><tbody>' + tr2 + '</tbody></table>');
                        }
                    } else {	// insert new row

                        opts.finder.getTr(target, index + 1, 'body', 2).before(tr2);
                    }
 
                    data.total += 1;
                    data.rows.splice(index, 0, row);
 
                    this.refreshRow.call(this, target, index);
                },
 
                deleteRow: function (target, index) {
                    var state = $.data(target, 'datagrid');
                    var opts = state.options;
                    var data = state.data;
 
                    opts.finder.getTr(target, index).remove();
                    for (var i = index + 1; i < data.rows.length; i++) {
                        var tr2 = opts.finder.getTr(target, i, 'body', 2);
                        tr2.attr('datagrid-row-index', i - 1);
                        tr2.attr('id', state.rowIdPrefix + '-2-' + (i - 1));
