What did you do?
I added a banner image to the document's .headerLeft and a table in the .headerLeft. The table has an Image to the left and Text to the right of the image.
document.add(.headerLeft, image: bannerPDFImage)
document.add(.headerLeft, table: headerTable)
What did you expect to happen?
I expected to see the full image and text beneath the banner image. Instead, there's a gap between the banner image and table below, with the top of the table cut off.
What happened instead?
