ElementUI的el-table固定表头高度自适应

1.表格设置:height="tableHeight"
<el-row class="tablediv" ref="tableContainer">
  <el-col :span="24">
    <el-table :data="tableData" highlight-current-row border :height="tableHeight">
      <el-table-column type="index" label="序号" width="60" align="center"/>
      <el-table-column prop="enterprisecode" label="企业编号" header-align="center" width="120" sortable="custom"></el-table-column>
      <el-table-column prop="enterprisename" label="企业名称" header-align="center"></el-table-column>
      <el-table-column prop="projectname" label="项目名称" header-align="center" sortable="custom"></el-table-column>
    </el-table>
  </el-col>
</el-row>

2.data配置

data: function () {
  return {
    tableHeight: 0, // 表格高度
    tableData: []

  };
},

3.mounted中代码

mounted() {
  this.$nextTick(function () {
    // 表格高度自适应
    const rect = this.$refs.tableContainer.$el.getBoundingClientRect();
    this.tableHeight = rect.height
    // 监听窗口大小变化
    let _this = this;
    window.onresize = function() {
      // 表格高度自适应
      const rect = _this.$refs.tableContainer.$el.getBoundingClientRect();
      _this.tableHeight = rect.height
    }
  })
}
