我用的vue.js的easy-table組件，最后一列不想加數(shù)據(jù)，是編輯和刪除2個按鈕，應該怎么寫一下

看看這個demo

<template>
    <v-table
            is-horizontal-resize
            style="width:100%"
            :columns="columns"
            :table-data="tableData"
            row-hover-color="#eee"
            row-click-color="#edf7ff"
            @on-custom-comp="customCompFunc"
    ></v-table>
</template>

<script>

    import Vue from 'vue'

    export default{
        data() {
            return {
                tableData: [
                        {"name":"趙偉","tel":"156*****1987","hobby":"鋼琴、書法、唱歌","address":"上海市黃浦區(qū)金陵東路569號17樓"},
