3.上述代码中对于IText字体设置可改：
使⽤iText中的字体
例：BaseFont.createFont("STSong-Light", "UniGB-UCS2-H",BaseFont.NOT_EMBEDDED);
使⽤Windows系统⾃带的字体
例：BaseFont.createFont("C:/WINDOWS/Fonts/SIMYOU.TTF", BaseFont.IDENTITY_H,BaseFont.NOT_EMBEDDED); 使⽤外部引⼊的资源字体(
例：BaseFont.createFont("/SIMYOU.TTF", BaseFont.IDENTITY_H,BaseFont.NOT_EMBEDDED);
4.上述代码⽣成的表格边框隐藏⽅式：
1：代表上边框
2：代表下边框
4：代表左边框
8：代表右边框
//需要隐藏那些边框就把对应的值加起来，得到的和就是要设置的值
//⽐如要隐藏左右边框就是 4+8=12
cell.disableBorderSide(12);//左右没了
具体例⼦：
//隐藏上边框
cell.disableBorderSide(1);
//隐藏下边框
cell.disableBorderSide(2);
//隐藏左、上边框
cell.disableBorderSide(5);
//隐藏左、下边框
cell.disableBorderSide(6);
//隐藏左、上、下边框
cell.disableBorderSide(7);
//隐藏右边框
cell.disableBorderSide(8);
//隐藏右、上边框
cell.disableBorderSide(9);
//隐藏右、下边框
cell.disableBorderSide(10);
//隐藏右、上、下边框
cell.disableBorderSide(11);
//隐藏左、右边框
cell.disableBorderSide(12);//左右没了 //隐藏上、左、右边框
cell.disableBorderSide(13);//只剩下 //隐藏下、左、右边框
cell.disableBorderSide(14);//只剩上//隐藏全部
cell.disableBorderSide(15);//全没了5.运⾏展⽰效果
