[英]how to create complex table from json using angular 6?
我正在嘗試從給定的 json 創建表。 這是 json 結構。 我正在使用簡單的 html 表來使表結構與下面快照中提到的相同。因為數據是動態表結構在我的情況下顯示不正確。
{
"e_id": "1234",
"e_o_name": "Contact_info",
"matching_details": [
{
"me_value": "value1",
"matching_attributes": [
{
"me_id": "1234",
"me_name": "28 sai",
"me_list": [
{
"me_type": "Email ID",
"me_email_list": [
{
"me_value": "a@gmail"
},
{
"me_value": "b@gmail"
}
],
"me_percent": "100"
}
]
},
{
"me_id": "5678",
"me_name": "29 meena",
"me_list": [
{
"me_type": "Email ID",
"me_email_list": [
{
"me_value": "c@gmail.com"
},
{
"me_value": ",d@gmail.com"
}
],
"me_percent": "100"
}
]
}
]
},
{
"me_value": "value2",
"matching_attributes": [
{
"me_id": "1234",
"me_name": "rimzim",
"me_list": [
{
"me_type": "Email ID",
"me_email_list": [
{
"me_value": "p@gmail"
},
{
"me_value": "q@gmail"
}
],
"me_percent": "100"
}
]
},
{
"me_id": "5678",
"me_name": "ranu",
"me_list": [
{
"me_type": "Email ID",
"me_email_list": [
{
"me_value": "t@gmail.com"
},
{
"me_value": ",u@gmail.com"
}
],
"me_percent": "100"
}
]
}
]
},
]}
上面的結構是實際輸出。我嘗試創建相同的但對我來說數據是單行的。
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>
同樣的幫助是高度appriciated ...提前致謝
我會准備適當的表格行結構以呈現這個復雜的表格。
組件.ts(或服務.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;
}
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>
</tbody>
</table>
