How to color a row or cell of a grid depending on it's data in Vaadin 14

To fix this issue In Vaadin 14 Style a Grid row based on data
First, you need to set the CSS class name generator for the row. This will add the CSS class name to the td elements created by Grid. The generator function receives your item and you should return a CSS class name as a String or null if you don't want to add a class name for certain rows. Multiple class names can be returned from the generator as space-separated.
code :
grid.setClassNameGenerator(person -> {
    if (person.getStatus() == Status.DIVORCED || person.getStatus() == Status.SINGLE) {
        return "my-style-1";
    } else {
        return "my-style-2";
td.my-style-1 {
    background-color: black;
    color: hotpink;

td.my-style-2 {
    background-color: hotpink;
    color: black;
@CssImport(value = "./styles/styles.css", themeFor = "vaadin-grid")
public class MainView extends VerticalLayout {
// your code for grid
grid.getColumnByKey("status").setClassNameGenerator(person -> {
    if (person.getStatus() == Status.SINGLE) {
        return "my-style-3";
    return null;

this one helps. I suggest using getRowClass with applying extra cls to needed columns:
code :
Ext.create('Ext.grid.Panel', {
    columns: [
        // ...
        { header: 'Change', dataIndex: 'change', tdCls: 'x-change-cell' },
        // ...

    viewConfig: {
        getRowClass: function(record, index) {
            var c = record.get('change');
            if (c < 0) {
                return 'price-fall';
            } else if (c > 0) {
                return 'price-rise';
    // ...
.price-fall .x-change-cell {
    background-color: #FFB0C4;
.price-rise .x-change-cell {
    background-color: #B0FFC5;

I hope this helps you . You have two options to style the content of a Grid in Vaadin.
First, to set the style of a row, you can do the following:
code :
grid.setStyleGenerator(stockRow -> 
  "1".equals(stockRow.getValue1()) ? "highlighted" : null);
.v-grid-row.highlighted {
  color: red;
.v-treegrid-row.highlighted > td {
  color: red;
  .setStyleGenerator(stockRow -> {
    switch (stockRow.getValue1()) {
      case "1": return "red";
      case "3": return "yellow";
      case "5": return "green";
      default: return null;
.v-grid-cell.red {
  color: red;
