最近做移动端的h5项目，要做一个可配置表头的复杂表格，网上找了很久也没什么好方法，结合网上的一些例子，在此做一了一个完整的vue版的例子
效果图
1.引入 iscroll
npm i iscroll --save
2.对插件再做一层封装，封装成 iscrollTable.js 方便调用，代码如下：
// 统一使用
const iScollProbe = require('iscroll/build/iscroll-probe');
let scroller = null;
let Selector = "";
export function createIScroller(selector) {
Selector = selector;
scroller = new iScollProbe(Selector, {
preventDefault: false, // 阻止浏览器滑动默认行为
probeType: 3, //需要使用 iscroll-probe.js 才能生效 probeType ： 1 滚动不繁忙的时候触发 probeType ： 2 滚动时每隔一定时间触发 probeType ： 3 每滚动一像素触发一次
mouseWheel: true, //是否监听鼠标滚轮事件。
scrollX: true, // 启动x轴滑动
scrollY: true, // 启动y轴滑动
// momentum: false,
lockDirection: false,
snap: false, //自动分割容器，用于制作走马灯效果等。Options.snap:true// 根据容器尺寸自动分割
//snapSpeed: 400,
scrollbars: false, //是否显示默认滚动条
freeScroll: true, //主要在上下左右滚动都生效时使用，可以向任意方向滚动。
deceleration: 0.0001, //滚动动量减速越大越快，建议不大于 0.01,默认:0.0006
disableMouse: true, //是否关闭鼠标事件探测。如知道运行在哪个平台，可以开启它来加速。
disablePointer: true, //是否关闭指针事件探测。如知道运行在哪个平台，可以开启它来加速。
disableTouch: false, //是否关闭触摸事件探测。如知道运行在哪个平台，可以开启它来加速。
eventPassthrough: false, //使用 IScroll 的横轴滚动时，如想使用系统立轴滚动并在横轴上生效，请开启。
bounce: false //是否启用弹力动画效果，关掉可以加速
});
scroller.on('scroll', updatePosition);
scroller.on('scrollEnd', updatePosition);
scroller.on('beforeScrollStart', function () {
scroller.refresh();
});
function updatePosition() {
let frozenCols = document.querySelectorAll(selector + ' table tr td.cols');
let frozenRows = document.querySelectorAll(selector + ' table tr th.rows');
let frozenCrosses = document.querySelectorAll(selector + ' table tr th.cross');
for (let i = 0; i < frozenCols.length; i++) {
frozenCols[i].style.transform = 'translate(' + -1 * this.x + 'px, 0px) translateZ(0px)';
}
for (let i = 0; i < frozenRows.length; i++) {
frozenRows[i].style.transform = 'translate(0px, ' + -1 * this.y + 'px) translateZ(0px)';
}
for (let i = 0; i < frozenCrosses.length; i++) {
frozenCrosses[i].style.transform = 'translate(' + -1 * this.x + 'px,' + -1 * this.y + 'px) translateZ(0px)';
}
}
return scroller;
}
export function refreshScroller() {
if (scroller === null) {
console.error("先初始化scroller");
return;
}
setTimeout(() => {
scroller.refresh();
scroller.scrollTo(0, 0);
let frozenCols = document.querySelectorAll(Selector + ' table tr td.cols');
let frozenRows = document.querySelectorAll(Selector + ' table tr th.rows');
let frozenCrosses = document.querySelectorAll(Selector + ' table tr th.cross');
for (let i = 0; i < frozenCols.length; i++) {
frozenCols[i].style.transform = 'translate(0px, 0px) translateZ(0px)';
}
for (let i = 0; i < frozenRows.length; i++) {
frozenRows[i].style.transform = 'translate(0px, 0px) translateZ(0px)';
}
for (let i = 0; i < frozenCrosses.length; i++) {
frozenCrosses[i].style.transform = 'translate(0px, 0px) translateZ(0px)';
}
}, 0);
}3.引用前面的自己封装的iscrollTable.js，用到的table.vue的具体代码如下：
<template>
<div class="pages-tables " id="pages-tables">
<div class="rolling-table meal-table" ref="tableBox" :style="{height: maxHeight + 'px'}">
<table class="table" id="table" cellpadding="0" cellspacing="0" ref="rollingTable">
<tr v-for="(x,i) in xList" :key="i">
<th class="rows " :class="{'cross': index == 0 && i == 0}" v-for="(l,index) in x" :key="index" :colspan="l.colspan" :rowspan="l.rowspan">{{l.name}}</th>
</tr>
<tr v-for="(l,i) in yList" :key="i + 'a'">
<template v-for="(x, xKey) in xField">
<td v-for="(ll,yKey) in l" :key="yKey" v-if="x === yKey" :class="{'cols': yKey == xField[0]}">
{{ yList[i][yKey]}}
</td>
</template>
</tr>
<tr></tr>
</table>
<van-empty class="empty" v-if="yList.length==0" description="暂无数据" />
<div :class="[arrow=='left'?'arrows-body-left':'', 'arrows-body']" v-if="yList.length>0">
<div class="arrow"></div>
<div class="arrow"></div>
<div class="arrow"></div>
</div>
</div>
</div>
</template>
