用vue3实现在表格中嵌套echarts

要在表格中嵌套echarts，你可以使用Vue3的Composition API，将表格和echarts分别封装为组件，然后在一个父组件中将它们组合起来。以下是一个简单的示例：

1. 首先，在main.js中引入echarts：

import * as echarts from 'echarts';
import { createApp } from 'vue';
import App from './App.vue';

const app = createApp(App);
app.config.globalProperties.$echarts = echarts;
app.mount('#app');

2. 创建一个Table组件和一个Echarts组件，分别用来展示表格和图表：

// Table.vue
<template>
  <table>
    <thead>
      <tr>
        <th v-for="header in headers">{{ header }}</th>
      </tr>
    </thead>
    <tbody>
      <tr v-for="(row, index) in rows" :key="index">
        <td v-for="(cell, index) in row" :key="index">{{ cell }}</td>
        <td>
          <Echarts :data="chartData[index]" />
        </td>
      </tr>
    </tbody>
  </table>
</template>

<script>
import { ref } from 'vue';
import Echarts from './Echarts.vue';

export default {
  props: {
    headers: {
      type: Array,
      required: true,
    },
    rows: {
      type: Array,
      required: true,
    },
    chartData: {
      type: Array,
      required: true,
    },
  },
  components: {
    Echarts,
  },
};
</script>

// Echarts.vue
<template>
  <div ref="chart" style="width: 100%; height: 100%"></div>
</template>

<script>
import { ref, onMounted, watch } from 'vue';

export default {
  props: {
    data: {
      type: Object,
      required: true,
    },
  },
  setup(props) {
    const chartRef = ref(null);

    onMounted(() => {
      const chart = props.$echarts.init(chartRef.value);
      chart.setOption(props.data);
    });

    watch(
      () => props.data,
      () => {
        const chart = props.$echarts.getInstanceByDom(chartRef.value);
        chart.setOption(props.data);
      },
    );

    return {
      chartRef,
    };
  },
};
</script>

3. 最后，在父组件中引入Table和Echarts组件，并将它们组合起来：

<template>
  <div>
    <Table :headers="headers" :rows="rows" :chartData="chartData" />
  </div>
</template>

<script>
import { reactive } from 'vue';
import Table from './Table.vue';

export default {
  components: {
    Table,
  },
  setup() {
    const headers = ['Name', 'Age', 'Gender'];
    const rows = [
      ['Alice', 25, 'Female'],
      ['Bob', 30, 'Male'],
      ['Charlie', 35, 'Male'],
    ];
    const chartData = reactive([
      {
        xAxis: {
          type: 'category',
          data: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
        },
        yAxis: {
          type: 'value',
        },
        series: [
          {
            data: [120, 200, 150, 80, 70, 110, 130, 90, 170, 240, 150, 200],
            type: 'line',
          },
        ],
      },
      {
        xAxis: {
          type: 'category',
          data: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
        },
        yAxis: {
          type: 'value',
        },
        series: [
          {
            data: [50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160],
            type: 'line',
          },
        ],
      },
      {
        xAxis: {
          type: 'category',
          data: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
        },
        yAxis: {
          type: 'value',
        },
        series: [
          {
            data: [10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120],
            type: 'line',
          },
        ],
      },
    ]);

    return {
      headers,
      rows,
      chartData,
    };
  },
};
</script>

这样，就可以在表格中嵌套echarts了。你可以根据实际需求进行修改和调整。
