上面的结构是实际输出。我尝试创建相同的但对我来说数据是单行的。
enter code here<table>
<tbody>
<tr>
<th>contact</th>
<th>ty</th>
<th>ed</th>
<th>mail</th>
<th>percent</th>
</tr>
<tr>
<td rowspan="4">data.e_o_name</td>
<td rowspan="2" *ngFor="let match of data.matching_details">{{match.me_value}}</td>
<td>28 sai</td>
<th>a@gmail,b@gmail</th>
<td>100</td>
</tr>
</tbody>

I would prepare proper table rows structure in order to render this complex table.我会准备适当的表格行结构以呈现这个复杂的表格。
component.ts(or service.ts)组件.ts(或服务.ts)
rows = [];
generateTable() {
if (!this.data) {
return;
}
this.rows.push([
{
text: this.data.e_o_name,
rowspan: 0
}
]);
let maxRowSpan = 0;
this.data.matching_details.forEach((detail, i) => {
const elemRowSpan = Math.max(detail.matching_attributes.length, 1);
maxRowSpan += elemRowSpan;
if (i > 0) {
this.rows.push([])
}
this.rows[this.rows.length - 1].push({
text: detail.me_value,
rowspan: elemRowSpan
});
detail.matching_attributes.forEach((attr, j) => {
if (j > 0) {
this.rows.push([])
}
const mail = attr.me_list[0];
this.rows[this.rows.length - 1].push(
{
text: attr.me_name,
rowspan: 1
},
{
text: mail.me_email_list.map(({ me_value }) => me_value).join(', '),
rowspan: 1
},
{
text: mail.me_percent,
rowspan: 1
}
);
})
});
this.rows[0][0].rowspan = maxRowSpan;
}
template.html模板.html
<table>
<tbody>
<tr>
<th>contact</th>
<th>ty</th>
<th>ed</th>
<th>mail</th>
<th>percent</th>
</tr>
<tr *ngFor="let row of rows">
<td *ngFor="let col of row" [attr.rowSpan]="col.rowspan">{{ col.text }}</td>
</tr>
