Style style =new Style();
style.setAttributeValue(CellStyleAttributes.BACKGROUND_COLOR,GUIHelper.COLOR_RED);
style.setAttributeValue(CellStyleAttributes.BORDER_STYLE,new BorderStyle(2,GUIHelper.COLOR_RED,LineStyleEnum.SOLID));
configRegistry.registerConfigAttribute(EditConfigAttributes.VALIDATION_ERROR_STYLE,style, DisplayMode.EDIT);

If you use the RenderErrorHandling you should see in the code that changing the border is not supported in there. So you need to extend it to add that support.

Feel free to provide a patch to add that support to NatTable core directly.

That is a Java topic.

MyRenderErrorHandler extends RenderErrorHandler

and then do whatever you want to do.

I've tried it ,I think it's useful, but I have another problem before solving it. SWT Text don't have API to set border. I have to solve this first. thanks again
