先上效果图：

本文包含了具名插槽、作用域插槽、jsx语法三种：

Render.vue（很重要，必须有）:

<script>
export default {
  name: "FreeRender",
  functional: true,
  props: {
    scope:Object,
    render: Function
  },
  render: (h, ctx) => {
    console.log(222,ctx.props.render);// 通过打印会发现render函数会自动用h函数进行包裹
    return ctx.props.render ? ctx.props.render( ctx.props.scope) : "";
  }
};
</script>

Table.vue

<template>
  <div>
    <el-table :data="tableData" style="width: 100%" 
    :stripe="stripe" :border="border" :size="size"
    v-loading="loading"
    @selection-change="handleSelectionChange"
    >
    <!-- 是否支持复选 -->
    <el-table-column v-if="isSelection" width="55" type="selection" />
      <el-table-column
        :prop="item.param"
        :label="item.label"
        v-for="(item, index) in tableColumns"
        :key="index"
        :sortable="item.sortable"
        :width="item.width"
      >
        <template slot-scope="scope">
           <div v-if="item.render2">
             <Render
             :scope='scope.row'
             :render="item.render2"
            >
            </Render>
           </div>
          <slot v-else-if="item.slotName" :name="item.slotName" :row2="scope.row"></slot>
          <span v-else>{{scope.row[item.param]}}</span>
        </template>
      </el-table-column>
      <!-- 操作 -->
      <el-table-column v-if="tableOperation.label" :label="tableOperation.label">
        <template slot-scope="scope">
            <slot :name="tableOperation.param" :scope="scope">
              <el-button
                size="small"
                v-for="(item, index) in tableOperation.btnList"
                :key="index"
                @click="handleClick(scope.row, item.type)">
                {{item.label}}
              </el-button>
            </slot>
        </template>
      </el-table-column>
    </el-table>
   
  </div>
</template>
<script>
import Render from "@/components/Render";
export default {
  name: "Table",
  props: {
    tableColumns: {
      type: Array,
      required: true,
      default: () => {
        return []
      }
    },
    tableData: {
      type: Array,
      required: true,
      default: () => {
        return []
      }
    },
    tableOperation: {
      type: Object,
      default: () => {
        return {}
      }
    },
    stripe: {
      type: Boolean,
      default: true
    },
    border: {
      type: Boolean,
      default: true
    },
    size: {
      type: String,
      default: 'small'
    },
    loading: {
      type: Boolean,
      default: false
    },
    isSelection: {
      type: Boolean,
      default: false,
    }
  },
  components:{
    Render,
  },
  data() {
    return {
      h:'',
    }
  },
  methods: {
    handleClick(row, type) {
      this.$emit('handleClick', row, type)
    },
    handleSelectionChange(val) {
      this.$emit('handleSelectionChange', val)
    }
  }

使用Table组件

//html
    <Table
      :tableData="tableData"
      :isSelection="true"
      :tableColumns="tableColumns"
      :tableOperation="tableOperation"
      @handleClick="handleClick"
      @handleSelectionChange="handleSelectionChange"
    >
     <template #infoInput="scope">
       <el-input v-model="scope.row2.info"></el-input>
      </template>
    
    </Table>
// data & methods
 tableData: [
        {
          date: "2016-05-02",
          name: "王小虎",

      tableOperation: {
