如何在 Stepper angular 11 材料中对齐表单输入

如何解决如何在 Stepper angular 11 材料中对齐表单输入

我正在遵循角材料步进器 https://material.angular.io/components/stepper/examples 的示例。

<mat-horizontal-stepper [linear]="isLinear" #stepper="matHorizontalStepper">
  <mat-step [stepControl]="firstFormGroup">
    <form [formGroup]="firstFormGroup">
      <ng-template matStepLabel>Fill out your name</ng-template>
      <mat-form-field>
        <input matInput placeholder="Last name,First name" formControlName="firstCtrl" required>
      </mat-form-field>
      <div>
        <button mat-button matStepperNext>Next</button>
      </div>
    </form>
  </mat-step>
  <mat-step [stepControl]="secondFormGroup">
    <form [formGroup]="secondFormGroup">
      <ng-template matStepLabel>Fill out your address</ng-template>
      <mat-form-field>
        <input matInput placeholder="Address" formControlName="secondCtrl" required>
      </mat-form-field>
      <div>
        <button mat-button matStepperPrevIoUs>Back</button>
        <button mat-button matStepperNext>Next</button>
      </div>
    </form>
  </mat-step>
  <mat-step>
    <ng-template matStepLabel>Done</ng-template>
    You are Now done.
    <div>
      <button mat-button matStepperPrevIoUs>Back</button>
      <button mat-button (click)="stepper.reset()">Reset</button>
    </div>
  </mat-step>
</mat-horizontal-stepper>

我想在第一步有八输入，在第二步七输入看一张这张图。

我怎样才能在我的步进器中对齐它。有什么想法吗？
