Java iText避免在页面跳转时剪切表格
我正在使用一个显示许多表格的pdf。当一张表与页面的其余部分不匹配时，单击“下一步”剪切该表并在下一页设置其余部分 我想，如果一个表不适合页面的其余部分，那么将其放在新页面上Java iText避免在页面跳转时剪切表格,java,itext,Java,Itext,我正在使用一个显示许多表格的pdf。当一张表与页面的其余部分不匹配时，单击“下一步”剪切该表并在下一页设置其余部分 我想，如果一个表不适合页面的其余部分，那么将其放在新页面上 我怎样才能做到这一点？有不同的方法可以做到这一点；这有三个选择： 计算表的高度，将其与剩余空间进行比较。在将表添加到文档之前计算表的高度时，高度始终为0，除非使用setTotalWidth（）和setLockedWidth（）定义表的宽度。您可以使用getVerticalPosition（）方法（在PdfWriter中）在
我怎样才能做到这一点？有不同的方法可以做到这一点；这有三个选择：
cb.endText（）；
cb.restoreState（）；
document.add（Chunk.NEWLINE）；
表.设置总宽度（555.0f）；
int sNo=1；
float tableHeight1=table.getTotalHeight（）；
系统输出打印LN（表高1）；
int rowCount=2；
int-yAxis=570；
int newPageYAxis=0；
虽然（我非常感谢布鲁诺，这对我帮助很大：）附言：我刚刚意识到你写了这本iText书，非常荣幸：Dtable.keepRowsTogether非常有用！代码不完整，也没有解释代码的作用。你能改进一下吗？
