You will need to create geometry objects in an arbitrary coordinate space and then create text objects in there. Pass those on to a PDFPageFormatter to place them on the page.
There’s a TableAdder custom transformer on the FME Hub that you can try, I’ve had mixed results with it myself.
Thank you! I have used the transformers tableAdder and PDFPageFormatter but I keep having issues with all the columns and rows written on top of eachother on one page. Does someone know how to solve this ?
