一、項目區域的介紹
各塊區域------
Title----報表名，只在第一頁顯示
pageHeader-----放頁碼，時間，創建人，每一頁都會顯示出來
columnHeader-----列名
detail----循環的數據，比如說我們直接從數據庫中得到數據，只用將字段拖到此區域，那麼就會將所有的這個字段的值進行循環了。
-----需要注意的是：table中因爲放了數據，也會將這些數據接着循環。到頭來，本來一個table已經將數據給循環完了，但是又由於detail的循環性質，將整個table又循環了。所以table是不能放在detail中的。這回循環table。
columnFooter-----可以用來統計此列數據。
pageFooter-------每頁底部都會顯示的，如頁碼
lastPageFooter----最後一頁的底部，如日期，簽名.....
Summary--------可能需要對幾頁（你的報表可能有幾個頁組成）的統計值。比如50個銷售記錄共佔用了3頁，那麼放置這些統計記錄的統計值最好的地方就是summary。 Summary只在最後一頁出現。
二、軟件使用
參考:https://jingyan.baidu.com/article/49ad8bce417c405834d8fac9.html
三、非數據源軟件使用（我自己 總結）
3.1動態數據顯示
3.2 table的數據賦值
四，java項目裏寫法

五、字體的選擇
這時候你會發現中文無法顯示
那你需要軟件導入字體，
同時，java項目依賴導入。
<dependency>
<groupId>com.song</groupId>
<artifactId>myfont</artifactId>
<version>1.0.0</version>
</dependency>
這個是手動打入maven本地
jar包，還有軟件的ttf我會提供
