每个数组值的Mat输入

Question

我在这里要做的是为每个使用ngFor的人显示输入框。但是，这只允许我从第一个输入框中进行选择，当我进行选择时，它将自动更新具有相同值的其余输入。谁能帮助我了解我在这里可能做错了什么，我希望能够从people数组中单独更新每个人的值

 <table>
        <tr>
            <td class="detailS">Hours</td>
            <td style="width: auto" nowrap class="opt">
                <mat-list>
                    <mat-list-item class="item"
                        *ngFor="let member of people.value; let i = index">
