How to Customize Cell Rendering in Ag-Grid React?

Discover how to enhance your Ag-Grid React tables with custom cell rendering. Ag-Grid is a versatile grid library that allows for flexible data display. One of its key features is the ability to customize cell rendering to meet your specific needs.

Cell Rendering in Ag-Grid React

Customizing cell rendering in Ag-Grid React offers countless possibilities. Ag-Grid provides built-in cell renderers for common use cases. For advanced customization, creating your own cell renderer allows you to display data as needed.

Creating Custom Cell Renderer Components

Creating a custom cell renderer in Ag-Grid React involves defining a React component that implements the ICellRendererParams interface. This interface includes a value property containing the cell data.

Here is an example of a custom cell renderer that displays the cell value in bold:

JsxCopy code
import React from 'react';

const CustomCellRenderer = (props) => {
  return <strong>{props.value}</strong>;
};

export default CustomCellRenderer;

Use this custom cell renderer by specifying it in your column definition:

JsxCopy code
{
  headerName: 'Custom Cell',
  field: 'customField',
  cellRendererFramework: CustomCellRenderer,
}

Adding Interaction to Custom Cell Renderers

Custom cell renderers can incorporate interactivity, such as buttons or icons. Below is a custom cell renderer example with a button that triggers an alert:

JsxCopy code
import React from 'react';

const InteractiveCellRenderer = (props) => {
  const handleClick = () => {
    alert('Button clicked!');
  };

  return <button onClick={handleClick}>{props.value}</button>;
};

export default InteractiveCellRenderer;

This interactive cell renderer can be added to a specific column in your Ag-Grid React table:

JsxCopy code
{
  headerName: 'Interactive Cell',
  field: 'interactiveField',
  cellRendererFramework: InteractiveCellRenderer,
}

Applying Styling to Custom Cell Renderers

Styling custom cell renderers is straightforward with CSS or inline styles. You can adjust the appearance of your cell based on the cell value.

Here is an example that changes the cell's background color conditionally:

JsxCopy code
import React from 'react';

const StyledCellRenderer = (props) => {
  const backgroundColor = props.value === 'High' ? 'red' : 'green';

  const style = {
    backgroundColor: backgroundColor,
    color: 'white',
    padding: '5px 10px',
  };

  return <div style={style}>{props.value}</div>;
};

export default StyledCellRenderer;

In this example, if the cell value is 'High', the background color will be red; otherwise, it will be green.

Customizing cell rendering in Ag-Grid React provides opportunities for creating dynamic and interactive tables. With custom cell renderer components, interactivity, and styling, you can fully control the data presentation in your applications.
