Adding classname to renderer doesn't work with v14.2.0

Hi team,

I tried to use a renderer to a cell using custom component. I used the addClassNameWhenNeeded hook that you have before.

When I implement it, it seems like it doesn’t apply the classname to the fixed column.

import Handsontable from 'handsontable';

export type RendererProps = {
	TD: HTMLTableCellElement;
	value: any;
	cellProperties: Handsontable.CellProperties;
};

export const addClassWhenNeeded = (props: RendererProps) => {
	const className = props.cellProperties.className;

	if (className !== void 0) {
		Handsontable.dom.addClass(props.TD, className);
	}
};

Hi @r.evangelio

It would be best if you could send a code demo where the problem is replicable, but can you tell me if the class is not applied at all to the cell, or just the CSS properties?

As far as I checked, the classes where applied if you don’t specify the fixedColumnStart property. It seems like it doesn’t apply it within the cloned table.

In this case you will probably need to add !important statement to the CSS properties to override the styling. Can you please check if that helped?

I actually solved this by using the beforeRenderer hook.

export const beforeRendererCallback: AddClassesToCells = (TD, row, column, prop, value, cellProperties) => {
	const className = cellProperties.className;

	if (className !== void 0) {
		Handsontable.dom.addClass(TD, className);
	}
};

Thank you for the update. I’m glad that you’ve found the solution. I will close this topic then.
