spreadJs实现基本的表格编辑 导入导出

需求：报表形式展示，根据时间获取接口返回的数据，绑定到用spreadJs实现的excel上面，这个excel能正常的编辑，导出，别的excel能导入进来

初体验只能去官方啃文档：
官方链接
把相应的依赖先装好：

//使用以下命令在项目中导入SpreadJS Vue模块：
npm install @grapecity/spread-sheets-vue
npm install @grapecity/spread-sheets
//使用以下命令在项目中导入Excel IO Vue模块和FileSaver Vue模块：
npm install @grapecity/spread-excelio
npm install file-saver --save

然后代码中进行实现初始化一个excel：

 <div>
      <gc-spread-sheets class="sample-spreadsheets" @workbookInitialized="initSpread">
        <gc-worksheet> </gc-worksheet>
      </gc-spread-sheets>
      <div class="options-container">
        <div class="option-row">
          <div class="inputContainer">
            <input type="file" id="fileDemo" class="input" @change="changeFileDemo" />
            <input type="button" id="loadExcel" value="import" class="button" @click="loadExcel" />
          </div>
          <div class="inputContainer">
            <input id="exportFileName" value="export.xlsx" class="input" @change="changeExportFileName" />
            <input type="button" id="saveExcel" value="export" class="button" @click="saveExcel" />
          </div>
        </div>
      </div>
    </div>

import相关依赖：

import '@grapecity/spread-sheets/styles/gc.spread.sheets.excel2016colorful.css'
import * as GC from '@grapecity/spread-sheets'
import { IO } from '@grapecity/spread-excelio'
import '@grapecity/spread-sheets-vue'
import { saveAs } from 'file-saver'

将用到的变量定义到data中：

 data () {
    return {
      hostClass: 'spread-host',
      reportData: [],
     }
    }

初始化excel

initSpread (spread) {
      this.spread = spread
      let sheet = this.spread.getActiveSheet()
      sheet.getCell(0, 0).vAlign(GC.Spread.Sheets.VerticalAlign.center)
      sheet.setValue(0, 0, '测试项目第一列')
      sheet.setValue(0, 1, 'xxxxxx')
      sheet.setValue(2, 4, '2022年3月')
      sheet.setValue(2, 12, 'xxxxx')
      sheet.setValue(3, 0, 'xxxx')
      sheet.setValue(3, 1, 'xxxx名称')
      sheet.setValue(3, 2, 'xxxx单位')
      sheet.setValue(3, 3, '序号')
      sheet.setValue(3, 4, '总xxxxx')
      sheet.setValue(3, 5, 'xxxxxxxx')
      sheet.setValue(4, 5, 'xxxxxxx')

      sheet.setValue(4, 10, 'xxxx')
      sheet.setValue(3, 11, 'xxxxx%')
      sheet.setValue(3, 12, 'xxxx%')
      sheet.setValue(3, 13, '备注')

      sheet.addSpan(0, 0, 3, 1)
      sheet.addSpan(0, 1, 1, 13)
      sheet.addSpan(3, 0, 2, 1)
      sheet.addSpan(3, 1, 2, 1)
      sheet.addSpan(3, 2, 2, 1)
      sheet.addSpan(3, 3, 2, 1)
      sheet.addSpan(3, 4, 2, 1)
      sheet.addSpan(3, 5, 1, 3)

      sheet.setColumnWidth(0, 200) //设置某一列的宽度
      var lineStyle = GC.Spread.Sheets.LineStyle.thin //设置线条样式为实线
      var lineBorder = new GC.Spread.Sheets.LineBorder('black', lineStyle)
      var sheetArea = GC.Spread.Sheets.SheetArea.viewport
      sheet.getRange(2, 0, 1, 14).setBorder(lineBorder, { bottom: true }, sheetArea) //设置第二行 从第0列到14列的底部边框
      sheet.getRange(3, 0, 2, 14).setBorder(new GC.Spread.Sheets.LineBorder('black', GC.Spread.Sheets.LineStyle.thin), { all: true })
        // sheet.getRange(6, 0, 1, 14).setBorder(lineBorder, { bottom: true }, sheetArea)
    },

获取动态数据：

	getReportData () {
      let date = this.queryParam.investDate__eq //动态绑定的日期
      if (date === undefined || date === null || date === '') {
        this.$message.warning('请选择日期！')
      } else {
        this.initQueryParam.investDate = date
        var url = 'xxxxxxxxxx'
        getAction(xxx, { fileUrl: url }).then((res) => {
          this.reportData = res.result
          let sheet = this.spread.getActiveSheet()
          this.spread.refresh()
          //定义绑定到excel上的数据格式data
          var data = {
            datasource: this.reportData[1]
          }
          var source = new GC.Spread.Sheets.Bindings.CellBindingSource(data)
          sheet.setDataSource(source)
          this.getExcelR(sheet) //创建动态数据table
          let leg = this.reportData[1].length
          sheet.getRange(5, 0, leg, 14).setBorder(new GC.Spread.Sheets.LineBorder('black', GC.Spread.Sheets.LineStyle.thin), { all: true })
          sheet.getRange(5, 0, leg, 4).backColor('#DCDCDC', { all: true })
          sheet.getRange(5, 4, 5, 9).backColor('#DCDCDC', { all: true })
        })
      }
    },

在excel上面具体的位置创建动态table：

	getExcelR (sheet) {
	//从第五行第0列开始创建
      var table = sheet.tables.add('tableRecords', 5, 0, 1, 14)
      table.autoGenerateColumns(true) //根据内容自适应表格
      var tableColumns = []
      var namesL = []
      var names = []
      this.reportData[1].forEach((item) => {
        for (var key in item) {
          namesL.push(key)
        }
      })
      for (var i = 0; i < namesL.length; i++) {
        names.push('column' + i)
        sheet.autoFitColumn(i)
      }

      names.forEach(function (data, index) {
        var tableColumn = new GC.Spread.Sheets.Tables.TableColumn()
        tableColumn.name(names[index])
        tableColumn.dataField(data)
        tableColumns.push(tableColumn)
      })

      table.bindColumns(tableColumns)
      table.bindingPath('datasource')
      table.bandColumns(true)
      table.style(null)

      // 隐藏表头
      table.showHeader(false)
      sheet.deleteRows(5, 1)
    },
