如何打印JTable？

我有一個在JTable中顯示的整個數據庫，我添加了一個打印按鈕，但是它的作用是將JTable中的數據轉換爲.csv文件，excel打開它並用戶可以打印它，但它看起來像很難看。有沒有辦法將JTable組件發送給打印機？如何打印JTable？

你試過：[JTable.print（）]（http://docs.oracle.com/javase/6/docs/api/javax/swing/JTable.html#print（））？ – aymeric

聽起來像一個智能按鈕:-)嚴重的是，作爲編碼器，你應該知道按鈕的作用（畢竟這是你的代碼）。如果它應該做其他事情，..代碼不同。順便說一句：側邊欄提到了可能對學習有用的類似問題。 – kleopatra

根據JTable有一種方法叫做print()。會很好地拯救你。見下圖： -

package com.tanyasis.librarymanager; 

import java.awt.HeadlessException; 
import java.awt.print.PrinterException; 
import java.text.MessageFormat; 

import javax.swing.JTable; 

/** 
* Used to provide printing information and adding information that might be 
* important in a page such as page header, contents and footer. This class 
* makes sure that all contents of a table fit in the given page. 
* 
* @author Tanyasis Mwanik 
* 
*/ 
public class PrintTable { 

    private JTable table; 
    private MessageFormat headerFormat, footerFormat; 

    /** 
    * Prints the table and provide post printing information to the user if it 
    * was succesful 
    * 
    * @param table 
    *   <code>JTable</code> to be printed 
    * @param tableTitle 
    *   <code>String</code> to be used as the table header/title 
    */ 
    public PrintTable(JTable table, String tableTitle) { 
     // TODO Auto-generated constructor stub 
     this.setTable(table); 
     // Sets the table header 
     headerFormat = new MessageFormat(tableTitle); 
     // Sets the table footer 
     footerFormat = new MessageFormat("Page {0}"); 

     try { 
      boolean complete = table.print(JTable.PrintMode.FIT_WIDTH, 
        headerFormat, footerFormat, true, null, true, null); 

      if (complete) { 
       new ConfirmationClass(
         "<html><h2>Records Printed Successfully</h2></html>"); 
      } 

     } catch (HeadlessException | PrinterException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
    } 

    /** 
    * @return the table 
    */ 
    public JTable getTable() { 
     return table; 
    } 

    /** 
    * @param table 
    *   the table to set 
    */ 
    public void setTable(JTable table) { 
     this.table = table; 
    } 
}
