安装和引入xlsx依赖包
npm install -S xlsx
import XLSX from 'xlsx'
excel表格显示
>
{{tableData.slice((currpage - 1) * pagesize , currpage * pagesize)[scope.$index][key]}}
//不需要分页的话 这段和上面 "tableData.slice..." 直接换成tableData即可
import XLSX from 'xlsx'
import axios from 'axios'
export default {
data() {
return {
currpage:1,
pagesize:20,
totalNum:0,
tableData: [],
card: [], // excel表格sheet的数组
cardActive: '', // excel表格当前显示的sheet
workbook: {},
};
},
mounted () {
this.showStandard('Doc/code.xlsx'); //通过服务器获取流
// this.readFile('code.xlsx') //获取前端public下的excel文件
},
}
获取excel的流文件
因为后台获取文件流是 .net core异步获取,所以这里用async 和 await 处理
// 获取后台的流文件
async showStandard(excelUrl){
var type = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"
var filePaths = []
filePaths.push(excelUrl)
let res = await this.$axios.post("/api/Base/DownFileZip",filePaths,{ responseType: 'arraybuffer' })
var data = new Uint8Array(res)
var workbook = XLSX.read(data, {type:"array"})
var sheetNames = workbook.SheetNames // 工作表名称集合
this.workbook = workbook
this.card = sheetNames
this.cardActive = sheetNames[0]
this.getTable(sheetNames[0])
},
// 获取前端的流文件
readFile(url) {
axios.get(url, {responseType:'arraybuffer'}).then((res) => {
var data = new Uint8Array(res)
var workbook = XLSX.read(data, {type:"array"})
var sheetNames = workbook.SheetNames // 工作表名称集合
this.workbook = workbook
this.card = sheetNames
this.cardActive = sheetNames[0]
this.getTable(sheetNames[0])
})
},
getTable (sheetName) {
this.Matches = []
this.currpage = 1
var worksheet = this.workbook.Sheets[sheetName]
this.tableData = XLSX.utils.sheet_to_json(worksheet)
//获取第一行(即表头)
var header = XLSX.utils.sheet_to_json(worksheet,{header:1})[0]
var tableTitle = this.tableData[0]
var table0 = {}
//这里对表头进行处理,因为获取的数据渲染表头是根据第一条数据,
//当excel文件中第一条数据有为空时,第一条数据没有此属性,数据就不渲染,所以把为空的属性设置成“”
for(var i=0;i
设置表格样式
//给表头添加标识
renderHeader(h,{column,$index}){
return h(
'div',{style:'width:100%'},[
h('span', column.label),
h('span', {
class: "floatCR",
style:'color:#0094CE;margin-left:15px;font-family:Eurostile Bold'
},1==$index?'C':(3==$index?'R':''))
],
);
},
//给列设置背景色
columnStyle({ row, column, rowIndex, columnIndex }) {
if (columnIndex ==1||columnIndex ==3)
{
return 'background:rgba(147, 195, 235,0.05);'
}
},
表格分页
handleSizeChange(val) {
this.pagesize = val
},
handleCurrentChange(val) {
this.currpage = val
},
第一次写,就是想记录一下,有不规范的地方还请各位大哥赐教,谢谢!
