Apache poi 项目符号和编号 [英] Apache poi bullets and numbering
问题描述
我正在使用 apache POI 将 word 文档转换为 pdf.我正在用动态数据填充表格行.一切正常,但我想做一些增强,即我想在每行数据之前添加一个项目符号.这是我用来填充表中行数据的 for 循环:
I am using apache POI for converting a word document into pdf. I am filling the table rows with dynamic data. Everything is working fine, but i want to do some enhancement that is i want to add a bullet before each row data. Here is a for loop i am using to fill the row data in the table:
for (String string : documentList) {
XWPFTableRow lnewRow = ltable.createRow();
XWPFTableCell lnewCell = lnewRow.getCell(0);
XWPFParagraph lnewPara =lnewCell.getParagraphs().get(0);
XWPFRun lnewRun = lnewPara.createRun();
lnewRun.setText(string);
}
谁能告诉我如何在每行数据前添加项目符号?
Can anyone please tell me how can i add a bullet before each row data?
推荐答案
已有多个创建 XWPFNumbering
的示例.在我看来,它们中的大多数都是不必要的复杂.所以让我们有一个最简单的解决方案:
There are multiple examples for creating XWPFNumbering
already. Most of them are unnecessary complex in my opinion. So let's have a simplest solution:
import java.io.File;
import java.io.FileOutputStream;
import org.apache.poi.xwpf.usermodel.*;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTTblWidth;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.STTblWidth;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTAbstractNum;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTLvl;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.STNumberFormat;
import java.util.ArrayList;
import java.util.Arrays;
import java.math.BigInteger;
public class CreateWordTableWithBulletList {
public static void main(String[] args) throws Exception {
XWPFDocument document = new XWPFDocument();
XWPFParagraph paragraph = document.createParagraph();
XWPFRun run=paragraph.createRun();
run.setText("The table:");
XWPFTable ltable = document.createTable(1,1);
ltable.getCTTbl().addNewTblGrid().addNewGridCol().setW(BigInteger.valueOf(5000));
CTTblWidth tblWidth = ltable.getRow(0).getCell(0).getCTTc().addNewTcPr().addNewTcW();
tblWidth.setW(BigInteger.valueOf(5000));
tblWidth.setType(STTblWidth.DXA);
ltable.getRow(0).getCell(0).getParagraphs().get(0).createRun().setText("The list:");
ArrayList<String> documentList = new ArrayList<String>(
Arrays.asList(
new String[] {
"documentList item 1",
"documentList item 2",
"documentList item 3"
}));
//your code with supplements
CTAbstractNum cTAbstractNum = CTAbstractNum.Factory.newInstance();
//Next we set the AbstractNumId. This requires care.
//Since we are in a new document we can start numbering from 0.
//But if we have an existing document, we must determine the next free number first.
cTAbstractNum.setAbstractNumId(BigInteger.valueOf(0));
///* Bullet list
CTLvl cTLvl = cTAbstractNum.addNewLvl();
cTLvl.setIlvl(BigInteger.valueOf(0)); // set indent level 0
cTLvl.addNewNumFmt().setVal(STNumberFormat.BULLET);
cTLvl.addNewLvlText().setVal("\u2022");
//*/
/* Decimal list
CTLvl cTLvl = cTAbstractNum.addNewLvl();
cTLvl.setIlvl(BigInteger.valueOf(0)); // set indent level 0
cTLvl.addNewNumFmt().setVal(STNumberFormat.DECIMAL);
cTLvl.addNewLvlText().setVal("%1.");
cTLvl.addNewStart().setVal(BigInteger.valueOf(1));
*/
XWPFAbstractNum abstractNum = new XWPFAbstractNum(cTAbstractNum);
XWPFNumbering numbering = document.createNumbering();
BigInteger abstractNumID = numbering.addAbstractNum(abstractNum);
BigInteger numID = numbering.addNum(abstractNumID);
for (String string : documentList) {
XWPFTableRow lnewRow = ltable.createRow();
XWPFTableCell lnewCell = lnewRow.getCell(0);
XWPFParagraph lnewPara = null;
if (lnewCell.getParagraphs().size() > 0) {
lnewPara = lnewCell.getParagraphs().get(0);
} else {
lnewPara = lnewCell.addParagraph();
}
lnewPara.setNumID(numID);
XWPFRun lnewRun = lnewPara.createRun();
lnewRun.setText(string);
}
//your code end
paragraph = document.createParagraph();
FileOutputStream out = new FileOutputStream("CreateWordTableWithBulletList.docx");
document.write(out);
out.close();
System.out.println("CreateWordTableWithBulletList written successully");
}
}
我的例子总是完整的例子.我已经用你的代码和我对它的补充标记了这个部分.
My examples are always complete examples. I have marked the part with your code and my supplements to it.
