在这里我使用Angular Material的事情是标签和文本没有正确对齐

<div class="example-container">
        <form class="example-container" [formGroup]="options">     
                <div class="column">
                        <div class="col-sm-5">                         
            <label>Server name </label>   
        </div>
        </div>
        <div class="column">
                <div class="col-sm-5">  
            <mat-form-field>
                    <input matInput placeholder="Data Entry" required>
                </mat-form-field>                   
            </div>
        </div>
