在每一个字段和他对应的内容都会有setColspan()方法来设置它所占的列；  
而行数默认是1行,所以在“相片”字段是需要3行的的时候，就必须用setRowspan(3)来设置；

setFixedHeight()是用来设置每一行的高度，可以自己设置；  
注意：在显示照片的地方，设置setPadding(),是照片对内边框的设置；  
           setBorder()是设置边框

在我写的这个打印pdf的代码中，遇到一个问题，当setPadding()和setBorder()一起使用的时候，相片的右边将会没有边框

原因有2个：1）是由于图片太大覆盖了边框；

2）由于设置setBorder(1)与后面的baseTable.addCell(baseTableCell);重复，所以边框会消失

所以一般情况，setBorder()的值一般为0，或不要设置这个值
