--extend.js代码

export default {
    name: 'TableExpand',
    functional: true,
    props: {
        row: Object,
        render: Function,
        index: Number,
        column: {
            type: Object,
            default: null
        }
    },
    render: (h, ctx) => {
        const params = {
            row: ctx.props.row,
            index: ctx.props.index
        };
        if (ctx.props.column) params.column = ctx.props.column;
        return ctx.props.render(h, params);
    }
};

2.以上是两个组件的代码，下面将介绍调用及传入数据的格式

--调用组件

引入组件，且注册组件

import BaseTable from '@/components/BaseTable/index.vue'
注册加入components
components: {
      BaseTable
    },

调用组件

 <BaseTable :api-service="informationApi" :grid-config="INFO_CONFIG.gridConfig"
                  :grid-btn-config="INFO_CONFIG.gridBtnConfig"
                  ref="crud" :grid-edit-width="80"
                  :is-async="true" :hide-edit-area="true">
        </BaseTable>

传入数据的Js数据格式：

const INFO_CONFIG = {
  gridConfig: [
    {label: '设备代码', prop: 'sbdm', width: '150'},
    {label: '设备名称', prop: 'sbmc'},
    {label: '型号规格', prop: 'xh'},
    {label: '计量单位', prop: 'jldw', filter: equipmentUnitFilter},
    {label: '类型', prop: 'lx'},
    {label: '厂家', prop: 'cj'},
    {label: '是否是计量设备', prop: 'sfjlsb', filter: filterJLSB},
    {label: '筹供单位', prop: 'cgdw', filter: filterGCDW},
    {label: '使用年限(月)', prop: 'synx'},
  ],
  //操作按钮
  gridBtnConfig: {
    create: false, update: false, delete: false, view: false
  }
}

注意informationApi:是API 调用地址，如果需要直接传入数据，需要更组件中的逻辑，apiService传入true,不需要请求数据，出入gridData=[],即表格显示的数据，组件中传入的参数都写了注释，根据需做出更改吧
