JQgrid Paging用group而不是row，怎么办？

Question

我正在使用jqGrid，我已经通过deparment进行了分页和分组，我有超过一千行，每个部门超过200行，我每页显示100行，所以每个页面都有问题我能看到只有一个组在页面中有前100个记录，当所有行完成后，可以看到其他组的部门。但实际上我想在第一页和扩展中显示所有组我想要显示前100条记录，然后分页和所有组相同。 JqG​​rid有可能吗？如果是，那怎么样？

我目前的代码是

var ParsedJson = JSON.parse(result.BatchRpt);
                jQuery("#tblBatchReport").jqGrid({
                    data: ParsedJson,
                    datatype: "local",
                    height: 'auto',
                    width: 'auto',
                    rowNum: 100,
                    rowList: [10, 20, 30, 50, 100],
                    colNames: ['Date', 'Time', 'CC #', 'Department', 'Amount', 'AuthCode', 'Invoice#'],
                    colModel: [
                        { name: 'BillDate', index: 'BillDate', width: 90, sorttype: "date", summaryType: 'count', summaryTpl: '({0}) total', resizable: false, },
                        { name: 'BillTime', index: 'BillTime', width: 90, sorttype: "date", resizable: false, },
                        { name: 'AccNo', index: 'AccNo', width: 130, resizable: false, },
                        { name: 'Department', index: 'Department', width: 100, resizable: false, },
                        { name: 'BillAmount', index: 'BillAmount', width: 80, align: "right", sorttype: 'number', formatter: 'number', summaryType: 'sum', resizable: false, },
                        { name: 'AuthCode', index: 'AuthCode', width: 100, resizable: false, },
                        { name: 'RegisterInvNo', index: 'RegisterInvNo', width: 100, resizable: false, },
                    ],
