EasyTable - Paragraph in a cell

Question

I am using your EasyTable library and it is fantastic, for my use it is better than itext7. I have only one problem. I'm trying to insert a paragraph with multiple lines inside a cell but it gives me an error. Here is my class.

The error is:


    Exception in thread "main" java.lang.NullPointerException

        } catch (IOException e) {
            System.out.println(e.getMessage());
        }
    }
}

Thank you.

it fails in `drawingContext.getPage().getAnnotations().forEach(PDAnnotation::constructAppearances);`, see https://github.com/vandeseer/easytable/blob/master/src/main/java/org/vandeseer/easytable/drawing/cell/ParagraphCellDrawer.java . Find out whether with your debugger if `drawingContext` is null, or if `drawingContext.getPage()` is null. (`PDPage.getAnnotations()` is never null) — Tilman Hausherr, Feb 19 '20 at 09:14

Vandaer suggested this solution:

TableDrawer tableDrawer = TableDrawer.builder()
            .contentStream(contentStream)
            .page(page) // <-- This was missing
            .startX((page.getMediaBox().getUpperRightX() - 200) / 2)
            .startY(page.getMediaBox().getUpperRightY() - 20)
            .table(myTable)
            .build();
