最近有個功能需要下載憑證，想偷懶，所以找到一個html2image的jar包，把html傳到後臺生成圖片給用戶下載。
問題來了， html2image 利用JEditorPane來渲染html，然後它不支持table關於邊框的設置，想了個辦法hack下，搞定了，具體辦法是設置table的背景爲黑色，設置td,th的背景爲白色，設置table的cellpadding="1" cellspacing="1"，這樣就能露出table的黑色背景，就是邊框啦，
還有一個問題，table的寬度一直控制不好，頁面顯示的正常，生成出來的圖片寬度就不對，沒辦法，就將原來的jar包找到，改了代碼，新添了傳入css樣式的方法，解決了這個問題。
