Angular ngx-datatable multiple data in one column

Question

I've got a little problem adding more then one prop to column in ngx-datatable:

columns = [
  { prop: 'semesterName', name: 'סמסטר', resizeable: false },
  { prop: 'eventName', name: 'מפגש', resizeable: false },
  { prop: 'when', name: 'מועד מפגש', resizeable: false },
  { prop: 'lecturerName', name: 'מרצה', resizeable: false },
  { prop: 'hugName', name: 'חוג', resizeable: false },
];

I need to display two props in one column. Like 'eventName' and 'when' in one column.

The model:

export class Course {
  semester: string;
  semesterName: string;
  courseObject: string;
  course: string;
  courseName: string;
  eventObject: string;
  event: string;
  eventName: string;
  hugName: string;
  dayOfWeek: string;
  dayOfWeekNum: string;
  where: string;
  when: string;
  lecturerName: string;
  lecturerEMail: string;
  authMembers: number;
  eventStatus: string;}

The Html:

<ngx-datatable[columns]="columns" [rows]="courses">
</ngx-datatable>

Thank you!

Figured it out:

To change column names - let-column
Formatting cell content (ex: Date) - let-value
Formatting with multiple properties Ex: Date - let-row

The template:

<ngx-datatable [rows]="courses">
        <ngx-datatable-column>
            <ng-template let-column="column" ngx-datatable-header-template>
                סמסטר
            </ng-template>
            <ng-template let-row="row" ngx-datatable-cell-template>
                {{row.semesterName}}
            </ng-template>
        </ngx-datatable-column>
        <ngx-datatable-column>
            <ng-template let-column="column" ngx-datatable-header-template>
                מפגש
            </ng-template>
            <ng-template let-row="row" ngx-datatable-cell-template>
                {{row.event}} <br> {{row.eventName}}
            </ng-template>
        </ngx-datatable-column>
        <ngx-datatable-column>
            <ng-template let-column="column" ngx-datatable-header-template>
                מועד מפגש
            </ng-template>
            <ng-template let-row="row" ngx-datatable-cell-template>
                {{row.where}} <br> {{row.when}}
            </ng-template>
        </ngx-datatable-column>
        <ngx-datatable-column>
            <ng-template let-column="column" ngx-datatable-header-template>
                מרצה
            </ng-template>
            <ng-template let-row="row" ngx-datatable-cell-template>
                <a href="mailto:{{row.lecturerEmail}}">{{row.lecturerName}}</a>
            </ng-template>
        </ngx-datatable-column>
        <ngx-datatable-column>
            <ng-template let-column="column" ngx-datatable-header-template>
                חוג
            </ng-template>
            <ng-template let-row="row" ngx-datatable-cell-template>
                {{row.hugName}}
            </ng-template>
        </ngx-datatable-column>
    </ngx-datatable>

No need for [columns] anymore - remove it from the template.

If you want to stick to the usage of columns and rows inputs, you can add the aggregated column to the rows themselves. Without mutating courses, the properties would look something like this:

const rows = courses.map(course => ({
  ...course,
  eventDetails: `${course.eventName} on ${course.when}`
}))

const columns = [
  { prop: 'eventDetails', name: 'Event', resizable: false },
  // the rest of your columns...
]
