- Element-UI三级表头动态写法
需求场景： 业务方希望有表格可以体现员工的考勤信息，要具体到上午下午，统计司机上下班打卡所产生的数据。产品提出想做成三级表头根据页面查询条件的年月去动态生成表格的表头。三级分别是月份日期，对应的星期，以及每天的上午以及下午。
效果如下：
Avue配置方式
通过对avue-crud组件的option的配置如下：
{
label: `${$this.month}月${$this.dateList[0].ri}日`, // 月份
headerAlign: 'center',
children: [
{
label: `星期${$this.dateList[0].xq}`,
headerAlign: 'center',
children: [
{
label: '上午',
prop: 'oneAmAttendance',
headerAlign: 'center',
props: { label: 'name', value: 'code' },
type: 'select',
dicData: $this.attendanceTypeList,
formatter: (row, value, label, column) => {
try {
let satData = ''
$this.attendanceTypeList.find((item) => {
if (item.code === row.oneAmAttendance) {
satData = item.name
}
})
return satData
} catch (e) {
console.log(e)
}
}
},
{
label: '下午',
prop: 'onePmAttendance',
headerAlign: 'center',
props: { label: 'name', value: 'code' },
type: 'select',
dicData: $this.attendanceTypeList,
formatter: (row, value, label, column) => {
try {
let satData = ''
$this.attendanceTypeList.find((item) => {
if (item.code === row.onePmAttendance) {
satData = item.name
}
})
return satData
} catch (e) {
console.log(e)
}
}
}
]
}
]
},
在data中声明需要的变量以及获取每个月天数以及对应星期的方法
data(){
return {
dateList: [], // 日期list
month: 0, // 选中的月份
dayNum: 0 // 选中月的天数
}
}
created(){
this.montInfo(GetYearLastMonth())
// 当前月的天数
const arr = GetYearLastMonth().split('-')
this.month = parseInt(arr[1])
this.dayNum = this.dayNumFn(parseInt(arr[0]), parseInt(arr[1]))
}
methods(){
// 月日以及对应的星期
montInfo(res) {
/**
* 获取一个月多少天，并获取月初星期几
*/
const daxier = ['一', '二', '三', '四', '五', '六', '日'];
const date = res ? new Date(res) : new Date()
const y = date.getFullYear()
const m = date.getMonth() + 1
var date2 = new Date(y, m, 0)
var rq = date2.getDate() // 日 本月最后一天
var xq = date2.getDay(); // 星期 本月第一天星期几 new Date(0).getDay()
var rq2 = rq % 7
if (rq2 === 0) {
xq = rq2 + 1
} else {
if (rq2 > xq) xq += 7
xq = xq - rq2
}
var data = [];
for (var i = 1; i <= rq; i++) {
data.push({
'ri': i,
'xq': daxier[xq]
})
xq = (++xq === 7) ? 0 : xq
}
this.dateList = data
},
// 获取选中月的天数
dayNumFn(year, month) {
return new Date(year, month, 0).getDate()
},
}
根据查询条件去切换表头
{
label: '年月',
search: true,
hide: true,
searchPlaceholder: '请选择年月',
searchClearable: false,
prop: 'yearMonth',
type: 'month',
// 日期组件格式化
format: 'yyyy-MM', // 展示值
// 单元格格式化
valueFormat: 'yyyy-MM', // value
searchDefault: GetYearLastMonth(),
pickerOptions: {
disabledDate: (time) => {
return time.getTime() > new Date(GetYearLastMonth()).getTime()
}
},
// 查询条件月份切换的同事重新渲染表头
change(value) {
// 当前月的天数
$this.montInfo(value.value)
const arr = value.value.split('-')
$this.month = parseInt(arr[1])
$this.dayNum = $this.dayNumFn(parseInt(arr[0]), parseInt(arr[1]))
}
},
因为不同的月份日期有不同，比如2月只有28天而1月有31天。所以大于28的日期需要单独处理一下
{
label: $this.dayNum > 28 ? `${$this.month}月${$this.dateList[28].ri}日` : '',
headerAlign: 'center',
hide: $this.dayNum < 28,
children: [
{
label: $this.dayNum > 28 ? `星期${$this.dateList[28].xq}` : '',
headerAlign: 'center',
children: [
{
label: '上午',
prop: 'twentyNineAmAttendance',
headerAlign: 'center',
props: { label: 'name', value: 'code' },
type: 'select',
dicData: $this.attendanceTypeList,
formatter: (row, value, label, column) => {
try {
let satData = ''
$this.attendanceTypeList.find((item) => {
if (item.code === row.twentyNineAmAttendance) {
satData = item.name
}

return satData
} catch (e) {
console.log(e)

}
})
return satData
} catch (e) {
console.log(e)
}
}
}
]
}
]
},
{

}
})
return satData
} catch (e) {
console.log(e)
}
}
}
]
}
]
},
{
label: $this.dayNum === 31 ? `${$this.month}月${$this.dateList[30].ri}日` : '',
headerAlign: 'center',
hide: $this.dayNum !== 31,
children: [

}
})
return satData
} catch (e) {
console.log(e)
}
}
}
]
}
]
},
Element-UI三级表头动态写法
element-ui的写法相对简单一些，因为配置项没办法进行遍历渲染。
template里面的写法
<el-table
:data="tableData"
style="width: 100%" >
<el-table-column
prop="month"
label="月份"
width="150"
header-align="center">
</el-table-column>
<!-- 这里使用遍历的形式来进行渲染 -->
<template v-for="(item,index) in dateList" >
<el-table-column :label="`${month}月${item.ri}日`" header-align="center" :key="'date' + index">
<el-table-column header-align="center" :label="`星期${item.xq}`" >
<el-table-column header-align="center" :prop="item.sw" label="上午" width="120" ></el-table-column>
<el-table-column header-align="center" :prop="item.xw" label="下午" width="120" ></el-table-column>
</el-table-column>
</el-table-column>
</template>
</el-table>
data中还是声明变量，methods中还是应用和上面类似的方法
data(){
return {
dateList: [], // 日期list
month: 0, // 选中的月份
dayNum: 0, // 选中月的天数
}
}
created() {
this.montInfo(GetYearLastMonth())
// 当前月的天数
const arr = GetYearLastMonth().split('-')
this.month = parseInt(arr[1])
this.dayNum = this.dayNumFn(parseInt(arr[0]), parseInt(arr[1]))
},
methods: {
// 月日以及对应的星期
montInfo(res) {
/**
* 获取一个月多少天，并获取月初星期几
*/
const daxier = ['一', '二', '三', '四', '五', '六', '日'];
// 这里是每个上午下午展示为不同的变量
const amArr = ['oneAmAttendance', 'twoAmAttendance', 'threeAmAttendance', 'fourAmAttendance', 'fiveAmAttendance', 'sixAmAttendance', 'sevenAmAttendance', 'eightAmAttendance', 'nineAmAttendance', 'tenAmAttendance', 'elevenAmAttendance', 'twelveAmAttendance', 'thirteenAmAttendance', 'fourteenAmAttendance', 'fifteenAmAttendance', 'oneAmAttendance', 'twoAmAttendance', 'threeAmAttendance', 'fourAmAttendance', 'fiveAmAttendance', 'sixAmAttendance', 'sevenAmAttendance', 'eightAmAttendance', 'nineAmAttendance', 'tenAmAttendance', 'elevenAmAttendance', 'twelveAmAttendance', 'thirteenAmAttendance', 'fourteenAmAttendance', 'fifteenAmAttendance', 'sixteenAmAttendance', 'seventeenAmAttendance', 'eighteenAmAttendance', 'nineteenAmAttendance', 'twentyAmAttendance', 'twentyOneAmAttendance', 'twentyTwoAmAttendance', 'twentyThreeAmAttendance', 'twentyFourAmAttendance', 'twentyFiveAmAttendance', 'twentySixAmAttendance', 'twentySevenAmAttendance', 'twentyEightAmAttendance', 'twentyNineAmAttendance', 'thirtyAmAttendance', 'thirtyOneAmAttendance']
const pmArr = [
'onePmAttendance', 'twoPmAttendance', 'threePmAttendance', 'fourPmAttendance', 'fivePmAttendance', 'sixPmAttendance', 'sevenPmAttendance', 'eightPmAttendance', 'ninePmAttendance', 'tenPmAttendance', 'elevenPmAttendance', 'twelvePmAttendance', 'thirteenPmAttendance', 'fourteenPmAttendance', 'fifteenPmAttendance', 'onePmAttendance', 'twoPmAttendance', 'threePmAttendance', 'fourPmAttendance', 'fivePmAttendance', 'sixPmAttendance', 'sevenPmAttendance', 'eightPmAttendance', 'ninePmAttendance', 'tenPmAttendance', 'elevenPmAttendance', 'twelvePmAttendance', 'thirteenPmAttendance', 'fourteenPmAttendance', 'fifteenPmAttendance', 'sixteenPmAttendance', 'seventeenPmAttendance', 'eighteenPmAttendance', 'nineteenPmAttendance', 'twentyPmAttendance', 'twentyOnePmAttendance', 'twentyTwoPmAttendance', 'twentyThreePmAttendance', 'twentyFourPmAttendance', 'twentyFivePmAttendance', 'twentySixPmAttendance', 'twentySevenPmAttendance', 'twentyEightPmAttendance', 'twentyNinePmAttendance', 'thirtyPmAttendance', 'thirtyOnePmAttendance'
]
const date = res ? new Date(res) : new Date()
const y = date.getFullYear()
const m = date.getMonth() + 1
var date2 = new Date(y, m, 0)
var rq = date2.getDate() // 日 本月最后一天
var xq = date2.getDay(); // 星期 本月第一天星期几 new Date(0).getDay()
var rq2 = rq % 7
if (rq2 === 0) {
xq = rq2 + 1
} else {
if (rq2 > xq) xq += 7
xq = xq - rq2
}
var data = [];
for (var i = 1; i <= rq; i++) {
data.push({
'ri': i,
'xq': daxier[xq]
})
xq = (++xq === 7) ? 0 : xq
}
data.map((item, index) => {
item.sw = amArr[index]
item.xw = pmArr[index]
})
this.dateList = data
},
// 获取选中月的天数
dayNumFn(year, month) {
console.log(new Date(year, month, 0).getDate())
return new Date(year, month, 0).getDate()
}
}
