Angular 7.1.4 HTML 避免复制粘贴重组

Question

所以我的 html 看起来像这样：

<div>
    <div>Lots of stuff that only appears in this component #1</div>
    <div>Lots of stuff that only appears in this component #2</div>
    <div>Lots of stuff that only appears in this component #3</div>
    <div>Lots of stuff that only appears in this component #4</div>
</div>

目前我正在研究 CSS 和布局，但这意味着我正在不断地重构 DOM：

<div>
    <div>
        <div>Lots of stuff that only appears in this component #1</div>
        Lots of stuff that only appears in this component #2
        <div>Lots of stuff that only appears in this component #3</div>
        Lots of stuff that only appears in this component #4
    </div>
</div>

或者类似的东西。

我查看了ng-template，但这似乎只适用于ngIf 和ngSwitch。

我真正想要的是这样的，每次布局更改时我都不必重新复制所有内容。 顺便说一句，假设我无法创建新组件并将其移动到该新组件中。

<div>
    <div copyFrom="#1"></div>
    <div>
        <div copyFrom="#2"></div>
        <div copyFrom="#3"></div>
    </div>
    <div copyFrom="#4"></div>
</div>
<div no-display name="#1">Lots of stuff that only appears in this component #1</div>
<div no-display name="#2">Lots of stuff that only appears in this component #2</div>
<div no-display name="#3">Lots of stuff that only appears in this component #3</div>
<div no-display name="#4">Lots of stuff that only appears in this component #4</div>

有没有办法做到这一点，这样我就不必复制粘贴内容，而只需复制粘贴对内容的引用？

我正在使用 Angular 7.1.4。

因为我不知道你可能需要什么来帮助我，所以这是ng --version的结果：

Angular CLI: 7.1.4
Node: 11.6.0
OS: darwin x64
Angular: 7.1.4
... cli, common, compiler, compiler-cli, core, forms
... language-service, platform-browser, platform-browser-dynamic
... router

您正在寻找NgTemplateOutlet

<div>
  <ng-container *ngTemplateOutlet="template1"></ng-container>
    <div>
      <ng-container *ngTemplateOutlet="template2"></ng-container>
      <ng-container *ngTemplateOutlet="template3"></ng-container>
    </div>
  <ng-container *ngTemplateOutlet="template4"></ng-container>
</div>

<ng-template #template1> ... </ng-template>
<ng-template #template2> ... </ng-template>
<ng-template #template3> ... </ng-template>
<ng-template #template4> ... </ng-template>
