先上完成的效果图:列是根据查询结果增加的
数据格式:
表头的数据取出:
data.data.foreach(element => {
this.thead.push({
品名: element.品名,
面取数: element.面取数,
lotno: element.lot
});
element table中:
<el-table-column
v-for="(item,index) in thead"
:prop="item.lotno"
:key="index"
align="center"
width="180"
>
<template slot="header">
<tr>
<td>{{item.品名}}</td>
</tr>
<tr>
<td>{{item.面取数}}</td>
</tr>
<tr>
<td @click="querylot(item.lotno)">
<el-link>{{item.lotno}}</el-link>
</td>
</tr>
</template>
</el-table-column>
表格内数据整理:
for (let index1 = 3;index1 < object.keys(结果_data[0]).length;index1++) {
let newmap = new map();
let datakey = object.keys(结果_data[0])[index1];
newmap.set("mode", datakey); //取出每个数组对象的键值
for (let index2 = 0; index2 < 结果_data_length; index2++) {
let datavalue = 结果_data[index2][object.keys(结果_data[0])[index1]];
if (datakey == "投入日期") {
datavalue = datavalue.slice(0, 10);
}
newmap.set(
结果_data[index2][object.keys(结果_data[index2])[0]],datavalue);//获得这个键对应的所有的值
}
左侧表头合并:需要注意的是,当有固定列的时候需要设置表格的max-height属性,不然会出现列空白
objectspanmethod({ row, column, rowindex, columnindex }) {
if (columnindex === 0) {
if (rowindex % this.tabledata.length === 0) {
return {
rowspan: this.tabledata.length,
colspan: 1
};
} else {
return {
rowspan: 0,
colspan: 0
};
}
}
}
表格导出:
import filesaver from "file-saver";
import xlsx from "xlsx";
output() {
alert(1);
let wb = xlsx.utils.table_to_book(document.queryselector("#mytable")); //mytable为表格的id名
let wbout = xlsx.write(wb, {
booktype: "xlsx",
booksst: true,
type: "array"
});
try {
filesaver.saveas(
new blob([wbout], { type: "application/octet-stream" }),
"sheet.xlsx"
);
} catch (e) {
if (typeof console !== "undefined") console.log(e, wbout);
}
return wbout;
}
