Element UI 之table表格表头过长使用点点…显示,并添加鼠标移入悬浮显示

Element UI 之table表格表头过长使用点点…显示,并添加鼠标移入悬浮显示

需求
在这里插入图片描述
鼠标移入表头
在这里插入图片描述
关键点:
1.样式中添加:(如果在scope中会不起作用)

.el-table .cell {
    word-break: keep-all !important;
    white-space: nowrap !important;
  }

2.在需要悬浮显示的表头文字过长处添加

:show-overflow-tooltip="true" // 表格中文字过长
:render-header="renderHeader" //表头中文字过长

在这里插入图片描述

3.methods中添加:

renderHeader(h, data) {
      return h("span", [
        h(
          "el-tooltip",
          {
            attrs: {
              class: "item",
              effect: "dark",
              content: data.column.label,
              placement: "top",
            },
          },
          [h("span", data.column.label)]
        ),
      ]);
    },

实现

<template>
  <div class="table-content">
    <el-table
      :data="tableData"
      height="440"
      :border="false"
      :cell-style="cellStyle"
      :header-cell-style="{
        background: '#1C2E45',
        height: '40px',
        padding: '0',
        color: '#a0b2d3',
      }"
    >
      <template v-for="(item, index) in tableColumn">
        <template v-if="item.prop == 'rank'">
