Angular Material Table Cell Formatting

Question

I'm using angular material table for displaying data and dyanmically binding the table header and table data. Is there any way to format particaular column's cell content dynamically?.

For example how can i format the value of amount column right aligned?

My code is as below :

<table mat-table [dataSource]="dataSource" class="" style="width: 100%;">

      <ng-container [matColumnDef]="col" *ngFor="let col of displayedColumns; let i = index">
        <th *matHeaderCellDef> {{displayedFields[i].name}}</th>
        <td mat-cell *matCellDef="let element"> {{ element[col] }} </td>
      </ng-container> 

      <tr mat-header-row *matHeaderRowDef="displayedColumns"></tr>
      <tr mat-row *matRowDef="let row; columns: displayedColumns;"></tr>
    </table>

And my data is like

[
  {
    "REFERENCE_ID": "ENT201810637610",
    "PRODUCT_TYPE": "IMPS",
    "CUSTOMER_REFERENCE": "CUS12123",
    "BENEFICIARY_NAME": "arun",
    "DEBIT_ACCOUNT": "100002258062",
    "AMOUNT": 342234,
    "STAGE_CODE": "FULLFILMENT",
    "STATUS_CODE": "NEW"
  },
  {
    "REFERENCE_ID": "ENT201808820426",
    "PRODUCT_TYPE": "IMPS",
    "CUSTOMER_REFERENCE": "12121",
    "BENEFICIARY_NAME": "Arun",
    "DEBIT_ACCOUNT": "32423424",
    "AMOUNT": 700,
    "STAGE_CODE": "INITIATION",
    "STATUS_CODE": "NEW"
  }
]

Answer 1

Best solution is to use selector in css as below where 'column_name' is the name you provide in 'matColumnDef'

.mat-column-'column_name'{
   //your custom css 
   text-align: right;
 }

if your column 'matColumnDef' is 'amount'

.mat-column-amount{
   //your custom css 
   text-align: right;
 }

If you want to style cells on a mat-table you can target every element inside by using the ::ng-deep CSS selector like this:

::ng-deep th.mat-header-cell{
    width: 140px;
    min-width: 140px;
}

You can also use [ngClass] to apply classes to a cell based on a condition like this:

 <ng-container matColumnDef="outcome">
  <th mat-header-cell *matHeaderCellDef mat-sort-header class="border"> Outcome </th>
  <td mat-cell *matCellDef="let element" class="font-weight-normal text-center text-capitalize"
  [ngClass]="[element.outcome == '' ? 'not-provided' : 'not-provided',
            element.outcome == 'stopped' ? 'provided-stoped' : 'not-provided']">{{element.outcome == '' ? "not provided" : "provided"}}</span> </td>
</ng-container>

and you just define the classes in your CSS file
