实现原理通过：borderTop定宽 + borderLeft/borderRight控制其形状（梯形或者三角形） ，然后用marginLeft调整他的位置从而组装成漏斗图。

可调节vue代码demo：

<template>
    <div class="chart-block" style="width: 265px;margin: 0 auto;">
        修改的梯形索引: <a-input v-model:value="index"  placeholder="修改的梯形索引"/>
        宽度: <a-input-number v-model:value="customerOverview[index].funnleWidth" placeholder="左右角度" /><br />
        左右角度: <a-input-number v-model:value="customerOverview[index].nextWidth" placeholder="左右角度" /><br />
        左右间距: <a-input-number v-model:value="customerOverview[index].left" placeholder="左右间距" /><br />
        梯形高度: <a-input-number v-model:value="customerOverview[index].top" placeholder="梯形高度" /><br />
        <a-button type="primary" @click="download()">打印</a-button>
        <div class="grid-content"  v-for="(item , cuIndex) in customerOverview" :key="cuIndex">
            <div class="funnelChart" style="position: relative;font-size: 16px;color: #fff;font-weight: bold;height: 0; text-align: center;"
                 :style="{width:item.funnleWidth+'px', marginLeft: item.left +'px',
  borderTop: item.top + 'px solid '+funnleColor[cuIndex],
  borderLeft:item.nextWidth+'px solid transparent',
  borderRight: item.nextWidth+'px solid transparent'}">
                <span :style="{top: cuIndex === 6 ? '-136px' : '-28px'}" style="position: absolute;left: 50%;transform: translateX(-50%);white-space: nowrap;">{{ item.text }}</span>
            </div>
        </div>
    </div>
</template>
<script lang="ts">
import {Vue, Component} from 'vue-facing-decorator';

@Component({})
export default class chart extends Vue {
    //  修改的索引
    index = 0;
    funnleColor = ['#3C6EF0', '#2CA6E1', '#26A872', '#FFBA12', '#FF6E4C', '#E1251B', '#9a91eb'];
