如何从左边的word文档给poi表边距 [英] How to give poi table margin from left word document

问题描述

我正在使用 POI 创建一个 Word 文档.我创建了一个表和一个标题.我想给表格留出左边距，所以我使用了以下代码:

I am creating a word document using POI. I have created a table and a header. I want to give left margin to table so I used this code:

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]

但是这段代码也给左边的标题留出了 200 的边距.我只想要桌子.提前致谢.

But this code also give 200 margin to header from left. I Want only for table. Thanks in Advance.

推荐答案

您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 setFooter 和 setHeader 是用于设置页眉距页面顶部和页脚距页面底部的距离.没有特殊设置可以仅为正文或页眉/页脚设置左距离.因此更改的左页边距也会影响页眉和页脚.

The page margins, you set using the code shown, are margins for the whole page. Headers and footers also are part of the page as well as the body. The additional settings setFooter and setHeader in page margins are settings for distances of the header from top and the footer from bottom of the page. There are no special settings to set left distance only for body or header/footer. So changed left page margins also affect the header and footer.

您所能做的就是为正文中的段落和表格设置额外的缩进.

All you could do is set additional indentations for paragraphs and tables in the body.

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 apache poi 4.1.0 进行测试，需要 FAQ-N10025.

This code is tested using apache poi 4.1.0 and needs the the full ooxml-schemas-1.4.jar as mentioned in FAQ-N10025.
