iview 表格数据加载及表格内容编辑应用

本次应用效果如

 点击“修改”触发表格行编辑：

 编辑行各单元格内容，完毕后点击保存按钮更新编辑内容至表格数据源。

---

 对行单元格的编辑通过公用方法 renderTableColumn 来渲染，若需对单元格做验证则需要再次扩展。

 renderTableColumn 的代码如下：其中，editName 是待编辑单元格临时存储变量的字符串，columnName是当前单元格对应的key

renderTableColumn (editName, columnName, h, { row, index }) {
      let edit
      if (this.editTableIndex === index) {
        this[editName] = row[columnName]
        edit = [h('Input', {
          props: {
            value: row[columnName]
          },
          on: {
            input: (val) => {
              this[editName] = val
            }
          }
        })]
      } else {
        edit = row[columnName]
      }
      return h('div', [edit])
    },

完整代码如下：

<template>
  <div style="padding:32px 64px">
    <h1>可编辑行</h1> <Button
      type="primary"
      @click="addRow"
    >添加一行</Button>
    <Table
      :data="data"
      :columns="tbColumns"
      border
    ></Table>
    <div class="main-page">
      <Page
        :total="totals"
        :page-size="pageSize"
        @on-change="change"
        show-elevator
        :current.sync="current"
        :page-size-opts="page_size_array"
        show-sizer
        show-total
        @on-page-size-change="handleChangeSize"
      ></Page>
    </div>
    {{data}}
  </div>
