CellMaker Images (Angular)

The CellMaker class provides a simple way to create custom cells of common types within a FlexGrid.

This sample shows how to use the CellMaker class to create cells with images.

The CellMaker.makeImage method gets the image's URL from the column binding. It allows you to set a label expression which is applied to the image element's "alt" attribute, which is important for accessibility.

You may also specify a handler for the image's click event.
