Answer 1

To render a border only one one side of a cell you need to configure the CustomLineBorderDecorator around your content painter. Additionally you need to apply a special label to the cells that should show such a border, that indicates which borders to paint. These labels are defined in CustomLineBorderDecorator itself.

The color of the border can either be set statically on creating the CustomLineBorderDecorator or dynamically via style attributes.

To have this only for specific columns and rows use labels. This is explained in our Getting Started Tutorial or ourStyling documentation .

The NatTable project provides an Example Application that gives various examples for all the configuration possibilities and features supported. The requested feature is for example shown in _4222_CellPainterExample
