新手上路,请多包涵

比如说,鼠标移动到其中一行,该行上边显示双击打开详细内容。这该怎么做呢?

通过cell-mouse-enter和cell-mouse-leave实现,参考下:

<template>
  <div id="app">
    <el-table :data="tableData" style="width: 100%" @cell-mouse-enter="enter" @cell-mouse-leave="leave">
      <el-table-column label="日期" width="180">
        <template slot-scope="scope">
          <i class="el-icon-time"></i>
          <span style="margin-left: 10px">{{ scope.row.date }}</span>
        </template>
      </el-table-column>
      <el-table-column label="姓名" width="180">
        <template slot-scope="scope">
          <el-popover trigger="hover" placement="top" :ref="'popover' + scope.row.id" >
            <p>姓名: {{ scope.row.name }}</p>
            <p>住址: {{ scope.row.address }}</p>
            <div slot="reference" class="name-wrapper">
              <el-tag size="medium">{{ scope.row.name }}</el-tag>
            </div>
          </el-popover>
        </template>
      </el-table-column>
      <el-table-column label="操作">
        <template slot-scope="scope">
          <el-button size="mini" @click="handleEdit(scope.$index, scope.row)">编辑</el-button>
          <el-button size="mini" type="danger" @click="handleDelete(scope.$index, scope.row)">删除</el-button>
        </template>
      </el-table-column>
    </el-table>
  </div>
</template>

<script>

export default {
  name: "app",
  data() {
    return {
      tableData: [
        {
          id: 1,
          date: "2016-05-02",
          name: "王小虎",
          address: "上海市普陀区金沙江路 1518 弄"
        },
        {
          id: 2,
          date: "2016-05-04",
          name: "王小虎",
          address: "上海市普陀区金沙江路 1517 弄"
        },
        {
          id: 3,
          date: "2016-05-01",
          name: "王小虎",
          address: "上海市普陀区金沙江路 1519 弄"
        },
        {
          id: 4,
          date: "2016-05-03",
          name: "王小虎",
          address: "上海市普陀区金沙江路 1516 弄"
        }
      ]
    };
  },
  methods: {
    handleEdit(index, row) {
      console.log(index, row);
    },
    handleDelete(index, row) {
      console.log(index, row);
    },
    enter(row, column, cell) {
      console.log(row)
      this.$refs['popover'+row.id].showPopper = true
    },
    leave(row,column,cell) {
      this.$refs['popover'+row.id].showPopper = false
    }
  }
};
</script>
