后端接口传回的数据格式如下图
需要依靠后端传回的数据控制表格样式

实现代码

<!-- 可视化配置-表格 -->
<template>
  <div class="tabulation_main" ref="myDiv">
    <!-- 尝试过在mounted中使用this.$refs.myDiv.offsetHeight,获取父元素高度赋值给height的方法,发现该值只能在created之前确定,且不为动态 -->
    <el-table
      :data="tableData"
      :stripe="tableStyleObj.tableStyle.stripe == 'true' ? true : false"
      :row-style="rowStyleHandle"
      :row-class-name="tableRowClassName"
      :border="tableStyleObj.tableStyle.border == 'true' ? true : false"
      v-model:align="tableStyleObj.tableStyle.bodyTextAlign"
      :show-header="tableStyleObj.tableStyle.showHeader == 'true' ? true : false"
      :header-cell-style="{
        color: tableStyleObj.tableStyle.headerColor,
        'font-size': tableStyleObj.tableStyle.headerFontSize + 'px',

      }"
      :header-row-class-name="headerRowClassName"
      :height="tableStyleObj.tableStyle.tableHeight + ''"
      style="width: 100%"
    >
      <!-- 固定序号列 -->
