Angular 7 : Eliminating indexing of column names in the UI

Question

I have implemented a dynamic table in angular 7. I am display the column headers and records vertically. If you notice the columnheaders are hardcoded in the component. I currently have around 57 columns that I am rendering and issue that I forsee is when a new column is introduced in the server or the sequence of the column changes. The current UI code looks very tied by index i.e magic numbers. Is there a better way to handle the UI rendering.

UI

<table class="fundClassesTable table-striped" border="1">
  <tr *ngFor="let c of ColumnNames">
    <th class="tableItem bold">{{ c }}</th>
    <ng-container *ngFor="let f of data">
         <ng-container *ngFor="let s of data1;">
             <ng-container *ngIf="f.Id == s.LegalParentClassId">  
      <td class="tableItem" *ngIf="c == ColumnNames[0]">{{f.Description}}</td>
      <td class="tableItem" *ngIf="c == ColumnNames[1]">{{f.AuditSummary}}</td>
      <td class="tableItem" *ngIf="c == ColumnNames[2]">{{f.Id}}</td>
    </ng-container>
     </ng-container> 
  </ng-container>

  </tr>
  </table>

Component

public ColumnNames: string[] = ['Legal Class Name', 'Last Edited' , 'Legal Class ID',''];

Answer 1

Seems like you'll have better luck with a better column model, something like:

public ColumnNames: {header:string, prop:string}[] = [ 
                                   {header: 'Legal Class Name', prop: 'Description'},
                                   {header: 'Last Edited', prop: 'AuditSummary'},
                                   {header: 'Legal Class ID', prop: 'Id'}];

then you can use the improved model in your table to dynamically display data:

<tr *ngFor="let c of ColumnNames">
    <th class="tableItem bold">{{ c.header }}</th>
    <ng-container *ngFor="let f of data">
      <td class="tableItem" >{{f[c.prop]}}</td>       
    </ng-container>
</tr>

Now if your data changes, you're at least working with typescript code instead of html template. You could even store this column definition on your server and update it without ever redeploying / modifying your front end code.

you could in theory extend this model to include other things like classes, cell templates to display, or other things like sort keys, width definitions, etc. Let your imagination run wild.

Here's a working fiddle:

Answer 2

Apply sorting to column before rendering.

constructor(){
  this.ColumnNames = Object.keys(this.data[0]).sort();
}
