关于前端:antdesignvue表格合并行

columns: [  { title: 'xxx', dataIndex: 'xxx', align: 'center', customRender: renderContent }],// 合并行mergeRow () {  var colTemp = {}  this.dataSource.map((item, index) => {    var key = `${item.riskName}:${item.riskDes}:${item.riskPlrLevel}`    if (colTemp[key]) {      col1.forEach(col => {        if (col.val === key) {          col.len++        }      })    } else {      colTemp[key] = 1      col1.push({        idx: index,        val: `${item.riskName}:${item.riskDes}:${item.riskPlrLevel}`,        len: 1      })    }  })},// 合并行var col1 = []const renderContent = (value, row, index) => {  const obj = {    children: value,    attrs: {}  }  var key = `${row.riskName}:${row.riskDes}:${row.riskPlrLevel}`  col1.forEach(col => {    if (col.val === key) {      if (col.idx === index) {        obj.attrs.rowSpan = col.len      } else {        obj.attrs.rowSpan = 0      }    }  })  return obj}
