fastadmin如何修改表格operate样式图标更改为文字

关于这块的话，只能重写edit按钮才可以

{field: 'operate1', title: __('Operate'),
                            table: table, events: Table.api.events.operate,
                            formatter: function (value, row, index) {
                                var that = $.extend({}, this);
                                var table = $(that.table).clone(true);
                                // $(table).data("operate-edit", null); // 列表页面隐藏 .编辑operate-edit  - 删除按钮operate-del
                                // $(table).data("operate-del", null); // 列表页面隐藏 .编辑operate-edit  - 删除按钮operate-del
                                that.table = table;
                                return Table.api.formatter.operate.call(that, value, row, index);
                            },
                            buttons: [
