问题 I have been trying to create PDF files using Itext PDF writer. I have found that Superscript (0,4,5,6,7,8,9) and Subscript (0,1,2,3,4,5,6,7,8,9) are not allowed in the default font.

问题 I am using a java version of this library and can't figure out how to set the cell's height. When I use cell.setFixedHeight() and passing any number less that 18 the content dissapears in output PDF file. Why? Thank you 回答1: Check whether the width and height given for document is not exceeds. Document document = new Document(PageSize.A4, 60, 60, 120, 80); and for cell height you have to give in float value for e.g Cell.setFixedHeight(45f); I hope this will help you to proceed further :-) 来源：
