XWPF - 删除单元格文字

时间:2016-02-05 21:23:19

标签: java apache-poi xwpf

我有一个包含单个表的.docx文件。我想删除第2行到结尾的所有文本。 但是,方法myTable.getRow(somecounter).getCell(somecounter2).setText("")不起作用,因为它只将“”连接到现有值。 我还尝试制作一个XWPFRun并从run.setText("")创建myTable.getRow(sc).getCell(sc2).getParagraphs().get(0).createRun(),但它也不起作用。

也尝试了this thread的解决方案,这次没有运气:(

如何轻松地从单元格中删除文本? 我的想法是从头开始创建一个新表,并用内容填充它,但它似乎非常艰巨。

答案 0 :(得分:1)

您的要求“从第2行删除所有文本到结尾”将有点复杂,因为Word表格单元格可以包含许多其他内容而不仅仅是文本。

考虑下表:

因此,如果要求从第2行删除所有内容,那么您可以简单地用新的单元格替换所有单元格。或者至少是那些只有空段落的那些。

import java.io.FileOutputStream;
import java.io.FileInputStream;

import java.util.List;

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

import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTTc;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTTc;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTP;

/*
needs the full ooxml-schemas-1.3.jar as mentioned in https://poi.apache.org/faq.html#faq-N10025
since the CTRowImpl is not fully shipped with poi-ooxml-schemas-3.13-*.jar
*/

public class WordCleanTableRows {

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

  FileInputStream fis = new FileInputStream("document.docx");
  XWPFDocument doc = new XWPFDocument(fis);

  List<XWPFTable> tables = doc.getTables();
  XWPFTable table = tables.get(0);

  XWPFTableRow[] rows = table.getRows().toArray(new XWPFTableRow[0]);
  for (int r = 0; r < rows.length; r++) {
   if (r > 0) {
    XWPFTableRow row = rows[r];
    CTTc[] cells = row.getCtRow().getTcList().toArray(new CTTc[0]);
    for (int c = 0; c < cells.length; c++) {
     CTTc cTTc = cells[c];
     //clear only the paragraphs in the cell, keep cell styles
     cTTc.setPArray(new CTP[] {CTP.Factory.newInstance()});
     cells[c] = cTTc;
    }
    row.getCtRow().setTcArray(cells);
    //System.out.println(row.getCtRow());
   }
  }

  doc.write(new FileOutputStream("new document.docx"));

 }
}

这需要https://poi.apache.org/faq.html#faq-N10025中提到的完整的ooxml-schemas-1.3.jar 由于CTROWImpl没有完全附带poi-ooxml-schemas-3.13 - * .jar。

如果没有完整的ooxml-schemas-1.3.jar,您只需删除除第一行以外的所有行并添加新行。

import java.io.FileOutputStream;
import java.io.FileInputStream;

import java.util.List;

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

public class WordCleanTableRows2 {

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

  FileInputStream fis = new FileInputStream("document.docx");
  XWPFDocument doc = new XWPFDocument(fis);

  List<XWPFTable> tables = doc.getTables();
  XWPFTable table = tables.get(0);

  XWPFTableRow[] rows = table.getRows().toArray(new XWPFTableRow[0]);
  for (int r = 0; r < rows.length; r++) {
   if (r > 0) {
    XWPFTableRow row = rows[r];
    table.removeRow(1); //remove second row. others shift upwards
    table.createRow(); //add new row at the end
   }
  }

  doc.write(new FileOutputStream("new document.docx"));

 }
}

修改

以下应该在没有ooxml-schemas-1.3.jar的情况下工作,并且和我的第一个例子一样。

import java.io.FileOutputStream;
import java.io.FileInputStream;

import java.util.List;

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

import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTP;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.STOnOff;

import java.math.BigInteger;

public class WordCleanTableRows3 {

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

  FileInputStream fis = new FileInputStream("document.docx");
  XWPFDocument doc = new XWPFDocument(fis);

  List<XWPFTable> tables = doc.getTables();
  XWPFTable table = tables.get(0);

  XWPFTableRow[] rows = table.getRows().toArray(new XWPFTableRow[0]);
  for (int r = 0; r < rows.length; r++) {
   if (r > 0) {
    XWPFTableRow row = rows[r];
    List<XWPFTableCell> cells = row.getTableCells();
    for (XWPFTableCell cell : cells) {
     //get CTTc and replace the CTPArray with one empty CTP
     cell.getCTTc().setPArray(new CTP[] {CTP.Factory.newInstance()});

     //set some default styles for the paragraphs in the cells:
     //http://grepcode.com/file/repo1.maven.org/maven2/org.apache.poi/ooxml-schemas/1.1/org/openxmlformats/schemas/wordprocessingml/x2006/main/CTParaRPr.java  
     CTP cTP = cell.getCTTc().getPArray(0);
     cTP.addNewPPr();
     cTP.getPPr().addNewRPr();
     cTP.getPPr().getRPr().addNewB().setVal(STOnOff.ON);
     cTP.getPPr().getRPr().addNewColor().setVal("FF0000");
     cTP.getPPr().getRPr().addNewSz().setVal(BigInteger.valueOf(40));
    }
   }
  }

  doc.write(new FileOutputStream("new document.docx"));

 }
}

org.openxmlformats.schemas.wordprocessingml.x2006.main.CTP随附poi-ooxml-schemas-3.13 - * .jar。
