一開始給的解決方案如下
$(‘#xx’).datagrid.(‘hideColumn’,’field’)
這也是easyui API中給出的解決方案，但是在這裡並不管用，後來向組裡的大神請教了以後，又換了另外一種方法
全部程式碼如下
{ field: ‘ck’, checkbox: true },
{
field: ‘LoginName’, title: ‘登入名’, align: ‘center’, width: 150
},
{
field: ‘UserName’, title: ‘顯示名’, align: ‘center’, width: 100
},
{
field: ‘TelPhoneNum’, title: ‘手機號’, align: ‘center’, width: 150
},
{
field: ‘Telephone’, title: ‘辦公電話’, align: ‘center’, width: 100
},
{
field: ‘RightOrgName’, title: ‘單位’, align: ‘center’, width: 150
},
{
field: ‘IP’, title: ‘IP地址’, align: ‘center’, width: 150
},
{
field: ‘EmailAddress’, title: ‘電子郵箱’, align: ‘center’, width: 200
},
{
field: ‘Sort’, title: ‘排序’, align: ‘center’, width: 200
}

                    ]],
                    pagination: true,
                    rownumbers: true,
                    singleSelect: true,
                    queryParams: {
                        condition: Condition,
                    },
                    onLoadSuccess: function () {
                        if (getcheckDBS == "1" && oAppId != 9) {
                            $('td[field="Telephone"]').hide();
                            $('td[field="IP"]').hide();
                            $('td[field="EmailAddress"]').hide();
                        }
                        if (getcheckDBS == "1") {
                            $('td[field="Telephone"]').hide();
                            $('td[field="IP"]').hide();
                            $('td[field="EmailAddress"]').hide();
                        }
                    }
