要向docx模板中添加多个表格,可以使用Apache POI库来实现。下面是示例代码:
```java
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.List;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFTable;
import org.apache.poi.xwpf.usermodel.XWPFTableRow;
import org.apache.poi.xwpf.usermodel.XWPFTableCell;
public class AddMultipleTablesToDocxTemplate {
public static void main(String[] args) throws IOException {
// Load the docx template
XWPFDocument document = new XWPFDocument(
AddMultipleTablesToDocxTemplate.class.getResourceAsStream("template.docx"));
// Get the placeholders for the tables
List<XWPFParagraph> paragraphs = document.getParagraphs();
XWPFParagraph table1Placeholder = paragraphs.get(0);
XWPFParagraph table2Placeholder = paragraphs.get(1);
// Create the first table
XWPFTable table1 = document.createTable(3, 3);
fillTable(table1);
// Replace the first placeholder with the first table
replaceParagraphWithTable(table1Placeholder, table1);
// Create the second table
XWPFTable table2 = document.createTable(4, 4);
fillTable(table2);
// Replace the second placeholder with the second table
replaceParagraphWithTable(table2Placeholder, table2);
// Save the modified document
FileOutputStream out = new FileOutputStream(new File("output.docx"));
document.write(out);
out.close();
document.close();
}
private static void fillTable(XWPFTable table) {
for (int i = 0; i < table.getNumberOfRows(); i++) {
XWPFTableRow row = table.getRow(i);
for (int j = 0; j < row.getTableCells().size(); j++) {
XWPFTableCell cell = row.getCell(j);
cell.setText("Row " + i + ", Column " + j);
}
}
}
private static void replaceParagraphWithTable(XWPFParagraph paragraph, XWPFTable table) {
paragraph.getCTP().setTbl(table.getCTTbl());
}
}
```
这个示例代码中,我们首先加载了一个docx模板,然后获取了模板中两个占位符的Paragraph对象。接着,我们创建了两个表格,并使用fillTable()方法填充了这些表格。最后,我们使用replaceParagraphWithTable()方法将占位符替换为对应的表格,并将修改后的文档保存到输出文件中。
