vue封装的可视化滚动表格组件

前言

在大屏数据可视化方面,我们经常会使用到表格组件,这次封装的是不带分页的表格组件,对于长列表表格,我们采用的是滚动轮播的形式向下滚动展示表格数据。组件的翻页滚动是基于 vue-awesome-swiper 二次封装去实现的。 滚动表格组件.gif

1. 安装相应第三方包

装包建议使用cnpm 或者 yarn ,不然速度会很慢

npm install swiper vue-awesome-swiper -S
复制代码

2. 引入vue-awesome-swiper轮播组件

  • 在main.js中引入相关的第三方组件
import VueAwesomeSwiper from 'vue-awesome-swiper';
import 'swiper/css/swiper.css';
...
Vue.use(VueAwesomeSwiper);
复制代码

3. 表格组件封装

  • 新建组件文件

  • 定义组件传入的属性

  • 定义的组件的数据
    1. currentActiveRow 当前组件表格选中的行数
    2. swiperOption 相关定义滚动轮播参数,具体可参考 vue-awesome-swiper
data() {
    return {
      currentActiveRow: 0,
      swiperOption: {
        autoHeight: true,
        direction: 'vertical',
        spaceBetween: 0,
        autoplay: {
          delay: 2500,
          disableOnInteraction: false,
          autoplayDisableOnInteraction: false
        },
        slidesPerView: 'auto',
        grabCursor: true,
        autoplayDisableOnInteraction: false,
        mousewheelControl: true
      }
    };
  },
复制代码
  • 模板页的编写
<template>
  <div
    class="table-wrapper"
    :style="{
      width: 'calc(' + widths.reduce((i, j) => `${i} + ${j}`) + ` + ${(widths.length - 1) * 6}px)`,
      height: `calc(${contentHeight} + 48px)`
    }"
  >
    <div class="table-header" v-if="showHeader">
      <span v-for="(it, i) in widths" :key="i" :style="{ width: widths[i] }">{{ titles[i] }}</span>
    </div>
    <div class="table-content" :style="{ height: contentHeight }">
      <swiper class="swiper" :options="swiperOption" ref="myBotSwiper">
        <swiper-slide v-for="(it, i) in dataList" :key="i">
          <div
            class="table-row"
            :class="{ stripe: i % 2 === 1, active: i === currentActiveRow }"
            @click="handleRowClick(it, i)"
            :style="{ height: tabelHeight }"
          >
            <span
              v-for="(ite, ind) in widths"
              :key="ind"
              :title="it[ind]"
              :style="{ width: widths[ind], height: tabelHeight }"
              >{{ it[ind] }}</span
            >
          </div>
        </swiper-slide>
      </swiper>
    </div>
  </div>
</template>
复制代码

4. 表格组件的点击监听

  • 在父类组件传入 change 事件,组件内点击触发
  • 如果 需要点击表格的行数据时 不让表格滚动,就相应的调用 swiperStop 方法;swiperStart 从当前开始滚动
methods: {
    handleRowClick(it, i) {
      this.currentActiveRow = i;
      const currentIt = this.data[i];
      this.$emit('change', currentIt);
    },
    // 控制表格停止滚动
    swiperStop() {
      this.myBotSwiper.autoplay.stop();
    },
    // 控制表格开始滚动
    swiperStart() {
      this.myBotSwiper.autoplay.start();
    }
  },
复制代码

    :style="{
      width: 'calc(' + widths.reduce((i, j) => `${i} + ${j}`) + ` + ${(widths.length - 1) * 6}px)`,
      height: `calc(${contentHeight} + 48px)`
    }"
  >
    <div class="table-header" v-if="showHeader">
      <span v-for="(it, i) in widths" :key="i" :style="{ width: widths[i] }">{{ titles[i] }}</span>
    </div>
    <div class="table-content" :style="{ height: contentHeight }">
      <swiper class="swiper" :options="swiperOption" ref="myBotSwiper">

          <div
            class="table-row"
            :class="{ stripe: i % 2 === 1, active: i === currentActiveRow }"
            @click="handleRowClick(it, i)"
            :style="{ height: tabelHeight }"
          >
            <span
              v-for="(ite, ind) in widths"
              :key="ind"
              :title="it[ind]"
              :style="{ width: widths[ind], height: tabelHeight }"
              >{{ it[ind] }}</span
            >
