getspan({ row, column, rowIndex, columnIndex }, dataSource) { var getSpanCount = function (dataItems, index, condition, isStart) { if (index < dataItems.length && (index == 0 || isStart || condition(dataItems[index - 1], dataItems[index]))) return 1 + getSpanCount(dataItems, index + 1, condition, false); return 0; }; var getRowSpanCount = function (rowIndex, dataItems, condition) { if (rowIndex == 0 || !condition(dataItems[rowIndex - 1], dataItems[rowIndex])) { return getSpanCount(dataItems, rowIndex, condition, true); } return 0; }; if (columnIndex == 0) { //合並第一列 return { rowspan: getRowSpanCount(rowIndex, dataSource, (x, y) => x.checkTypeId == y.checkTypeId), colspan: 1 }; } return { rowspan: 1, colspan: 1 } }
this.result 為 el-table 綁定的數據集, 表格多行合並的條件是 x.checkTypeId == y.checkTypeId
只替換上圖中三處紅色地方的代碼,即可實現行合並。
html:
<el-table :data="dataSource" :span-method="(param)=>getspan(param,dataSource)"
因我這里的el-table個數是動態的,數據源也是動態的,所以必須加一個參數,把 table 綁定的 data 傳進來,方法來自網友,這下這個方法就完美了
