只需要在 el-table-column 标签中添加:resizable="false"即可

<template>
  <div class="m-other-table-wrap">
    <el-table
      :data="tableData"
      border
      style="width: 100%"
      @header-dragend="handleHeaderDragend"
    >
      <el-table-column prop="date" label="日期" width="180" :resizable="false">
      </el-table-column>
      <el-table-column prop="name" label="姓名" width="180"> </el-table-column>
      <el-table-column prop="address" label="地址"> </el-table-column>
    </el-table>
  </div>
</template>

<script>
import './index.css'

export default {
  data() {
    return {
      tableData: [
        {
          date: '2016-05-02',
          name: '王小虎',
          address: '上海市普陀区金沙江路 1518 弄',
        },
        {
          date: '2016-05-04',
          name: '王小虎',
          address: '上海市普陀区金沙江路 1517 弄',
        },
        {
          date: '2016-05-01',
          name: '王小虎',
          address: '上海市普陀区金沙江路 1519 弄',
        },
        {
          date: '2016-05-03',
          name: '王小虎',
          address: '上海市普陀区金沙江路 1516 弄',
        },
      ],
    }
  },
  methods: {
    handleHeaderDragend(e) {
      console.log(e)
    },
  },
}
</script>
