POI 从控制台读取表格每行信息，通过POI向word写入表格

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();
}
}

运行结果:



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。
