iview表格设置表头： 使用 renderHeader在表头渲染按钮

使用 renderHeader 渲染表头的显示内容：

renderHeader: (h, params) => {
    return h('span', [
        h('Button', {
            props: {
                type: 'success',
                size: 'small'
            }
        }, this.arr1[0]),
        h('Button', {
            props: {
                type: 'error',
                size: 'small'
            }
        }, this.arr1[1])
    ]);
},

具体代码：

<template>
    <Table :columns="columns1" :data="data1"></Table>
</template>
<script>
    export default {
        data() {
            return {

                arr1: ['name', '姓名'],
                arr2: ["age", "年龄"],
                arr3: ["address", "地址"],

                columns1: [
                    {
                        renderHeader: (h, params) => {
                            return h('span', [
                                h('Button', {
                                    props: {
                                        type: 'success',
                                        size: 'small'
                                    }
                                }, this.arr1[0]),
                                h('Button', {
                                    props: {
                                        type: 'error',
                                        size: 'small'
                                    }
                                }, this.arr1[1])
                            ]);
                        },
                        key: 'name'
                    },
                    {
                        renderHeader: (h, params) => {
                            return h('span', [
                                h('Button', {
