el-table实现多行合并的效果,并可编辑单元格

背景

数据为数组包对象，对象里面有属性值是数组；无需处理数据，直接使用el-table包el-table的方法，通过修改el-table的样式直接实现多行合并的效果

html代码

<template>

js代码

主要是cellClick和handleBlur控制的，首先需要找到包裹el-input和展示表格文字的父div,然后通过点击父div和el-input的失去焦点事件控制内部这两个元素的显示和隐藏

scss样式

首先设置cell-content的基础样式；元素饿显示和隐藏就单独拿出来通过在事件中做切换


  <style lang='scss' scoped>

// 对elementplus的样式修改

    .rule-table:deep() .cell {
  padding-left: 0px;
  padding-right: 0px;
}

:deep(.el-table--border) {
  border: none;
}

.rule-table .no-border-table :deep()tr:last-child td {
  border-bottom: none;
}

:deep().el-table::before {
  width: 0%;
  height: 0px;
}
.rule-table .no-border-table :deep()th {
  border-right: none;
}
.rule-table .no-border-table :deep()td {
  border-right: none;
}



// 可编辑

.cell-content {
  cursor: pointer;
  .item__input {
    // display: none;
    width: 95%;
    /* 调整elementUI中样式 如果不需要调整请忽略 */
    .el-input__inner {
      height: 24px !important;
    }
    /* 调整elementUI中样式 如果不需要调整请忽略 */
    .el-input__suffix {
      i {
        font-size: 12px !important;
        line-height: 26px !important;
      }
    }
  }
  .item__txt {
    // display: block;
    box-sizing: border-box;
    line-height: 32px;
    padding: 0 9px;
  }
}
// 单独设置编辑状态和常规状态
.item-edit {
  .item__input {
    display: block;
  }
  .item__txt {
    display: none;
  }
}
.item-normal {
  .item__input {
    display: none;
  }
  .item__txt {
    display: block;
  }
}

  </style>
