其他博客里有个表格如下:

**三、 直接标志转移**  
指令格式                 机器码                    测试条件                       如...则转移    
JC                           72                           C=1                               有进位  
JNC                         73                          C=0                               无进位  
JZ/JE                       74                          Z=1                                零/    
JNZ/JNE                  75                         Z=0                               不为零/    
JS                           78                           S=1                                负号  
JNS                         79                          S=0                                正号  
JO                           70                          O=1                               有溢出  
JNO                         71                         O=0                               无溢出  
JP/JPE                     7A                        P=1                               奇偶位为偶  
JNP/IPO                   7B                        P=0                               奇偶位为奇

现在来用POI来实现将上面的表格写入到word中

代码如下：

package my;
    
    import java.io.File;
    import java.io.FileOutputStream;
    import java.io.IOException;
    import java.util.Scanner;
    import java.util.regex.Pattern;
    import org.apache.poi.hssf.record.SCLRecord;
    import org.apache.poi.xwpf.usermodel.XWPFDocument;
    import org.apache.poi.xwpf.usermodel.XWPFTable;
    import org.apache.poi.xwpf.usermodel.XWPFTableRow;
    
    public class ReadTablesToWord
    {
    	public static void main(String[] args) throws IOException
    	{
    		//创建docx文档对象
            XWPFDocument document = new XWPFDocument();
    
            // Write the Document in file system
            FileOutputStream out = new FileOutputStream(
            		new File("C:\\Users\\Administrator\\Desktop\\code.docx"));
            // create table
            XWPFTable table = document.createTable();
            Scanner scanner=new Scanner(System.in);
            boolean hasRow=false;
            while(scanner.hasNextLine())
            {
            	String line=scanner.nextLine();
            	//再输入一个回车符就结束了。
            	if(line.isEmpty())
            		break;
            	
            	//以空白符分割
            	String[] words=line.split("\\s+");
            	XWPFTableRow tableRow;
            	if(!hasRow)
    			{
    		        tableRow = table.getRow(0);
    			}
            	else
            	{
            		 tableRow = table.createRow();
            	}
            	for (int i=0;i<words.length;i++)
    			{
            		//第一行操作
            		if(!hasRow)
            		{
            			System.out.println("-----------------第一行-----------------");
            			System.out.println(words[i]);
            			if(i==0)
            				tableRow.getCell(0).setText(words[i]);
            			else
            				tableRow.addNewTableCell().setText(words[i]);
            			System.out.println("-----------------第一行-----------------");
            		}
            		else 
            		{
            			System.out.println("-----------------第"+i+"行-----------------");
            			System.out.println(words[i]);
            			 tableRow.getCell(i).setText(words[i]);
            			System.out.println("-----------------第"+i+"行-----------------");
    				}
    			}
            	hasRow=true;
            }
            
            document.write(out);
            out.close();
    	}
    }

可以看到生成的表格太丑了，自己按住表格右下角拖动调整就好啦。
