itextpdf设置页码_word页码相同怎么改

itextpdf设置页码_word页码相同怎么改项目需要样式比较复杂,刚开始因为时间比较紧所以采用了Itextpdf插件代码生成pdf,实话说过程十分繁琐,因为pdf文件样式比较多,表格也比较多,各种的表格,还有就是页眉页脚页码都要自己找页面位置坐标但是又不能像html那样方便更改查看样式,只能改一点导出来看看合适不,然后再改再导出来看。私下调研了很多,现在罗列一下我所用到的一些样式处理,希望可以帮助需要做这个功能的朋友少踩坑,少尝试,直接出完美pdf报告。封面首页封面右上角那个图片可以换成logo,我做的大概是这样的一个样子,上代码/

接下来是页眉页脚事件的代码PDFBUilder
因为页眉页脚都是带格式的,所以需要一点一点拼接起来,页眉中需要添加logo图片,位置是通过代码中的x,y坐标指定的

大概覆盖了大部分的功能,当然还有给字体加背景色,字体加颜色,和比较复杂的表格制作
比如需要将list中的数据按年份横排
