Alternating row colors in Angular Material tables

Is there a way to target the alternate rows within an Angular Material Table in order to apply different background colors to them?

I have configured my ClaimFileHistoryDataSource class as follows:

claimClientInformation: ClaimFileHistory[];
dataSource : ClaimFileHistoryDataSource;
displayedColumns = ['TypeImg', 'Description', 'Agent'];


export class ClaimFileHistoryDataSource extends DataSource<ClaimFileHistory> {

    constructor(private _claimFileHistory: ClaimFileHistory[]) {
      super();
    }

    connect(): Observable<ClaimFileHistory[]> {
      return Observable.of(this._claimFileHistory);
    }

    disconnect() {}
}

During NgInit, I retrieve necessary data from the service and populate the DataSource:

this._claimFileHistoryService.getClaimFileHistoryById().subscribe(response => {
  this.claimClientInformation = response;       
  this.dataSource = new ClaimFileHistoryDataSource(this.claimClientInformation);
});

The data retrieval process is functioning correctly.

In the HTML, the structure of the Mat-Table is defined like below:

    <mat-table #table [dataSource]="dataSource">

      <ng-container matColumnDef="TypeImg">
        <mat-cell *matCellDef="let row"><img [src]='row.TypeImg' height="40px"></mat-cell>
      </ng-container>

      <ng-container matColumnDef="Description">
        <mat-cell *matCellDef="let row">
          <div>
            <span class="d-block">{{row.Description}}</span>
            <span class="d-block">{{row.Date}}</span>
          </div>

        </mat-cell>
      </ng-container>

      <ng-container matColumnDef="Agent">
        <mat-cell *matCellDef="let row"> {{row.Agent}} </mat-cell>
      </ng-container>

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

I am particularly interested in understanding how to differentiate between odd and even table rows, and set unique background colors for each.

Answer №1

To add unique styling to alternate rows, include the CSS code below in your .css or .scss file:

.mat-row:nth-child(even){
    background-color: teal;
}
        
.mat-row:nth-child(odd){
    background-color: navy;
}

Answer №2

Presenting a fresh approach for future developers who stumble upon this query.

Material Angular has now introduced row indexes variables that can be utilized.

<mat-row *matRowDef="
              let row;
              let even = even; 
              columns: displayedColumns;" 
         [ngClass]="{gray: even}"></mat-row>

In your CSS stylesheet:

.gray { background-color: #f5f5f5 }

Other available properties include: index, count, first, last, even, and odd.

Further details can be found on Angular Docs, specifically in the section "Table showing each row context properties"

Answer №3

To dynamically change the color of rows based on certain conditions, you can utilize CSS styling.

For example, if a cell value equals 100, you can set the row's background color to red using the following code snippet:

<tr class="matheader-row" mat-row *matRowDef="let row; columns: displayColumns; 
let i = index; let even = even;" [class.rowStyle]="row['myColumn']=='100'"
[ngClass]="{rowcolor: even}">
</tr>

CSS Styling

.rowStyle{
background-color: red;
font-weight: bold;
}

This approach will be effective if your table columns include 'myColumn'. Additionally, by utilizing the 'even' property, you can apply different color styles using [ngClass]="{rowcolor: even}.

Answer №4

When utilizing themes, a transparent CSS style can enhance the overall look:

.mat-row:nth-child(odd){
  background: rgba(0,0,0,0.025);
}

Answer №5

Unfortunately, I found that none of the solutions above worked for me (I'm using multiTemplateDataRows). However, after making some adjustments to Gustavo Lopez's answer, I was able to get it to work as shown below:

<tr *matRowDef="
          let row;
          let index = dataIndex;
          columns: displayedColumns;" 
     [ngClass]="{alternate: index % 2 == 0 }"></tr>´

The CSS remains the same as in the previous answer:

.alternate { background-color: #f5f5f5 }

It appears that properties like odd, even, or index don't work when you are dealing with multiTemplateDataRows. Luckily, they have resolved this issue by introducing the dataIndex property (https://github.com/angular/components/issues/12793#issuecomment-415356860). Hopefully, this solution will be useful for others who are working with expandable rows.

Answer №6

Using Angular Material Version 16

.mat-mdc-row:nth-child(even) {
  background-color: #f1f1f1; /* Defines background color for even rows */
}

.mat-mdc-row:nth-child(odd) {
  background-color: #ffffff; /* Specifies background color for odd rows */
}

Answer №7

After trying the solutions provided by @mohit uprim and @Gustavo Lopes, I found success with fixing the issue on a Material Angular datatable. Whenever I hover over a row, it reverts back to its default white color and only changes to the new CSS color when I move the mouse away. To resolve this, adding the "important" flag did the trick:

.specific-class {
    background-color: green !important;
}

Answer №8

Don't forget to verify the template style in your browser. If the property is strikethrough, make sure to include '!important'
