这篇文章主要介绍vue中elment-ui table怎么合并上下两行相同数据单元格,文中介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们一定要看完!
html :
<el-table
:header-cell-
:data="ptableDate"
align="center"
border
v-loading="loading"
:height="tableHeight"
:span-method="objectOneMethod"
>
<el-table-column align="center" show-overflow-tooltip prop="projName" ></el-table-column>
<el-table-column align="center" show-overflow-tooltip prop="dirtySection" ></el-table-column>
<el-table-column align="center" show-overflow-tooltip prop="towerNumber" ></el-table-column>
<el-table-column align="center" show-overflow-tooltip prop="inclination" ></el-table-column>
</el-table>
method
objectOneMethod({ row, column, rowIndex, columnIndex }) {
if (columnIndex === 0) {
const _row = this.setTable(this.ptableDate).one[rowIndex];
const _col = _row > 0 ? 1 : 0;
return {
rowspan: _row,
colspan: _col
};
}
if (columnIndex === 1 ) {
const _row = this.setTable(this.ptableDate).two[rowIndex];
const _col = _row > 0 ? 1 : 0;
return {
rowspan: _row,
colspan: _col
};
}
},
setTable(tableData) {
let spanOneArr = [],
spanTwoArr = [],
concatOne = 0,
concatTwo = 0;
tableData.forEach((item, index) => {
if (index === 0) {
spanOneArr.push(1);
spanTwoArr.push(1);
} else {
if (item.projName === tableData[index - 1].projName) {
//第一列需合并相同内容的判断条件
spanOneArr[concatOne] += 1;
spanOneArr.push(0);
} else {
spanOneArr.push(1);
concatOne = index;
}
if (item.dirtySection === tableData[index - 1].dirtySection) {
//第二列和需合并相同内容的判断条件
spanTwoArr[concatTwo] += 1;
spanTwoArr.push(0);
} else {
spanTwoArr.push(1);
concatTwo = index;
}
}
});
return {
one: spanOneArr,
two: spanTwoArr
};
},
ps:下面看下ELEMENT-UI 合并单元格的方法
arraySpanMethod({ row, column, rowIndex, columnIndex }) {
// 只合并区域位置
//columnIndex 横的第一列
//rowIndex 竖的数组的length % 3 ==0 合并单元格
if (columnIndex === 0) { //如果是第一行
if (rowIndex % 3 === 0) {//如果是 数组长度 % 3 ==0
return {
rowspan: 3,
colspan: 1
};
} else {
return {
rowspan: 0,
colspan: 0
};
}
}
},
