요소 테이블 다단계 단위 행 병합

효과

테이블의 병원명을 기준으로 행을 병합한 후, 부서명을 기준으로 병합합니다.

JS

1.데이터

 table: [{
    
    
        id: '1',
        checkRoom: '安徽省立医院',
        checkProject: '颈椎MRICT',
        checkMoney: '300.22',
        attention: '检查前空腹',
        appointmentTime: '内科'
      },{
    
    
        id: '1',
        checkRoom: '安徽省立医院',
        checkProject: '颈椎MRICT1',
        checkMoney: '303.22',
        attention: '检查前空腹1',
        appointmentTime: '骨科'
      },{
    
    
        id: '1',
        checkRoom: '安徽省立医院',
        checkProject: '颈椎MRICT1',
        checkMoney: '303.22',
        attention: '检查前空腹2',
        appointmentTime: '骨科'
      },
      {
    
    
        id: '1',
        checkRoom: '安徽省立医院',
        checkProject: '颈椎MRICT1',
        checkMoney: '303.22',
        attention: '检查前空腹1',
        appointmentTime: '骨科'
      },
      {
    
    
        id: '1',
        checkRoom: '安徽中医院',
        checkProject: '颈椎MRICT22',
        checkMoney: '340.22',
        attention: '检查前空腹',
        appointmentTime: '骨科'
      },{
    
    
        id: '1',
        checkRoom: '安徽中医院',
        checkProject: '颈椎MRICT22',
        checkMoney: '340.22',
        attention: '检查前空腹1',
        appointmentTime: '骨科'
      },{
    
    
        id: '1',
        checkRoom: '安徽中医院',
        checkProject: '颈椎MRICT22',
        checkMoney: '340.22',
        attention: '检查前空腹',
        appointmentTime: '骨科'
      },{
    
    
        id: '1',
        checkRoom: '安徽中医院',
        checkProject: '鼻骨',
        checkMoney: '500.22',
        attention: '检查前空腹',
        appointmentTime: '骨科'
      }],

2. 먼저 monted에서 테이블을 처리합니다.

mounted() {
    
    
    this.getListDataForRowAndColumn(this.table)
  },
   getListDataForRowAndColumn(data){
    
    
      let self = this;
      self.rowAndColumn = [];
      self.rowRoomColumn = [];
      for (var i = 0; i < data.length; i++) {
    
    
        if (i === 0) {
    
    
          console.log(1)
          // 如果是第一条记录（即索引是0的时候），向数组中加入１
          self.rowAndColumn.push(1);
          self.pos = 0;
          self.rowRoomColumn.push(1);
          self.posT = 0;
        } else {
    
    
          //data[i].checkRoom就是你从接口读取的字段信息，下同
          if (data[i].checkRoom === data[i - 1].checkRoom) {
    
    
            console.log(data[i].checkRoom)
            // 如果checkRoom相等就累加，并且push 0
            self.rowAndColumn[self.pos] += 1
            self.rowAndColumn.push(0)
            if (data[i].appointmentTime === data[i - 1].appointmentTime) {
    
    
              console.log(data[i].appointmentTime)
              // 如果appointmentTime相等就累加，并且push 0
              self.rowRoomColumn[self.posT] += 1
              self.rowRoomColumn.push(0)
            } else {
    
    
              self.rowRoomColumn.push(1)
              self.posT = i
            }
          } else {
    
    
            // 不相等push 1
            self.rowAndColumn.push(1)
            self.pos = i;
            self.rowRoomColumn.push(1)
            self.posT = i
          }
        }
      }
      console.log(self)
    },

3. 행 병합

 objectSpanMethod({
     
      row, column, rowIndex, columnIndex }) {
    
    
      let self = this
      console.log(row, column, rowIndex, columnIndex)
      if (columnIndex === 0) {
    
    
        if (self.rowAndColumn[rowIndex]) {
    
    
          let rowNum = self.rowAndColumn[rowIndex];
          return {
    
    
            rowspan: rowNum,
            colspan: rowNum > 0 ? 1 : 0
          }
        }
        return {
    
    
          rowspan: 0,
          colspan: 0
        }
      }
      if (columnIndex === 1) {
    
    
        if (self.rowRoomColumn[rowIndex]) {
    
    
          let roomNum = self.rowRoomColumn[rowIndex];
          return {
    
    
            rowspan: roomNum,
            colspan: roomNum > 0 ? 1 : 0
          }
        }
        return {
    
    
          rowspan: 0,
          colspan: 0
        }
      }
    },
