Dynamic rowspan in angular

Number of persons and their mobiles numbers are dynamic. I need to show this in table.

Data can contain any number of pname and mobile numbers.

dataList = [

 {

  pname: "abc",

  numbers: [{mobile1: 123, mobile2: 234}]

 },

{

  pname: "mno",

  numbers: [{mobile1: 125, mobile2: 237}]

 }

]

Template

<tr *ngFor="let data of dataList">

 <td  [attr.rowspan]="data.numbers.lenght">data.pname</td>

 <td>data.numbers</td> // Here how do I show all mobile numbers of the person.

</tr>

Expected output is of below code.

table, th, td {

    border: 1px solid black;

}

<table>

  <tr>

    <th>Pname</th>

    <th>Numbers</th>

  </tr>

  <tr>

    <td rowspan="2">Abc</td>

    <td>123</td>

  </tr>

  <tr>

    <td>234</td>

  </tr>

  <tr>

    <td rowspan="2">Mno</td>

    <td>125</td>

  </tr>

  <tr>

    <td>237</td>

  </tr>

</table>

Problem I am facing is I need to add tr after each run of *ngFor and the number of tr will depend on length of numbers array to make row span.

You can do it like shown below

<table>        

    <ng-container *ngFor="let data of dataList">    

        <tr>

            <td [attr.rowspan]="data.numbers.length">{{data.pname}}</td>

            <td>{{data.numbers[0]}}</td>

        </tr>

        <ng-container *ngFor="let number of data.numbers; let i= index;">

            <tr *ngIf="i!=0">

                <td>{{number}}</td>

            </tr>

        </ng-container>

    </ng-container>

</table>

But datalist must be of the following format i.e. numbers must be an array

dataList = [

 {

  pname: "abc",

  numbers: [123, 234]

 },

{

  pname: "mno",

  numbers: [125,  237]

 }

]

You can do it like shown below

<table>        

    <ng-container *ngFor="let data of dataList">    

        <tr>

            <td [attr.rowspan]="data.numbers.length">{{data.pname}}</td>

            <td>{{data.numbers[0]}}</td>

        </tr>

        <ng-container *ngFor="let number of data.numbers; let i= index;">

            <tr *ngIf="i!=0">

                <td>{{number}}</td>

            </tr>

        </ng-container>

    </ng-container>

</table>

But datalist must be of the following format i.e. numbers must be an array

dataList = [

 {

  pname: "abc",

  numbers: [123, 234]

 },

{

  pname: "mno",

  numbers: [125,  237]

 }
