如何从左字文档给poi表边距

Question

我正在使用POI创建word文档。我已经创建了一个表和一个标题。我想给表格留左边距，所以我使用了以下代码：

CTSectPr getSectPr = doc.getDocument().getBody().getSectPr();
CTPageMar addNewPgMar = getSectPr.addNewPgMar();
addNewPgMar.setLeft(BigInteger.valueOf(200));
addNewPgMar.setRight(BigInteger.valueOf(200));
addNewPgMar.setFooter(BigInteger.valueOf(0));
addNewPgMar.setHeader(BigInteger.valueOf(0));
[![enter image description here][1]][1]

但是这段代码也给标题从左到右提供了200个边距。我只想要桌子。提前感谢。

Answer 1

使用所示代码设置的页边距是整个页面的边距。页眉和页脚也是页面和正文的一部分。页边距中的附加设置setFater和setHeader是页眉距页面顶部和页脚距页面底部的距离设置。没有特殊的设置来仅为正文或页眉/页脚设置左距离。所以左页边距的改变也会影响页眉和页脚。

您所能做的就是为正文中的段落和表格设置额外的缩进。

示例：

import java.io.FileOutputStream;

import org.apache.poi.xwpf.usermodel.*;
import org.apache.poi.wp.usermodel.HeaderFooterType;

import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTSectPr;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTPageMar;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTTblWidth;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.STTblWidth;

import java.math.BigInteger;

public class CreateWordHeaderFooter {

 public static void main(String[] args) throws Exception {

  XWPFDocument document = new XWPFDocument();

  // the body content
  XWPFParagraph paragraph = document.createParagraph();
  // set indentation of the paragraph
  paragraph.setIndentationLeft(720); //720 TWentieths of an Inch Point (Twips) = 720/20 = 36 pt = 36/72 = 0.5"
  XWPFRun run=paragraph.createRun();  
  run.setText("The Body:");

  paragraph = document.createParagraph();
  // set indentation of the paragraph
  paragraph.setIndentationLeft(720);
  run=paragraph.createRun();  
  run.setText("Lorem ipsum.... page 1");

  // create table
  XWPFTable table = document.createTable(3,3);
  // set indentation of the table
  CTTblWidth tableIndentation = table.getCTTbl().getTblPr().addNewTblInd();
  tableIndentation.setW(BigInteger.valueOf(720));
  tableIndentation.setType(STTblWidth.DXA);
  for (int row = 0; row < 3; row++) {
   for (int col = 0; col < 3; col++) {
    table.getRow(row).getCell(col).setText("row " + row + ", col " + col);
   }
  }

  paragraph = document.createParagraph();
  // set indentation of the paragraph
  paragraph.setIndentationLeft(720);

  // create header start
  XWPFHeader header = document.createHeader(HeaderFooterType.DEFAULT);

  paragraph = header.getParagraphArray(0);
  if (paragraph == null) paragraph = header.createParagraph();
  paragraph.setAlignment(ParagraphAlignment.LEFT);

  run = paragraph.createRun();  
  run.setText("The Header");

  // create footer start
  XWPFFooter footer = document.createFooter(HeaderFooterType.DEFAULT);

  paragraph = footer.getParagraphArray(0);
  if (paragraph == null) paragraph = footer.createParagraph();
  paragraph.setAlignment(ParagraphAlignment.LEFT);

  run = paragraph.createRun();  
  run.setText("The Footer");

  // create page margins
  CTSectPr sectPr = document.getDocument().getBody().getSectPr();
  if (sectPr == null) sectPr = document.getDocument().getBody().addNewSectPr();
  CTPageMar pageMar = sectPr.getPgMar();
  if (pageMar == null) pageMar = sectPr.addNewPgMar();
  pageMar.setLeft(BigInteger.valueOf(720)); //720 TWentieths of an Inch Point (Twips) = 720/20 = 36 pt = 36/72 = 0.5"
  pageMar.setRight(BigInteger.valueOf(720));
  pageMar.setTop(BigInteger.valueOf(720));
  pageMar.setBottom(BigInteger.valueOf(720));
  pageMar.setFooter(BigInteger.valueOf(720));
  pageMar.setHeader(BigInteger.valueOf(720));
  pageMar.setGutter(BigInteger.valueOf(0));

  FileOutputStream out = new FileOutputStream("CreateWordHeaderFooter.docx");
  document.write(out);
  out.close();
  document.close();

 }
}

此代码使用ApachePOI4.1.0进行测试，需要完整的ooxml-schemas-1.4.jar，如FAQ-N10025所述。
