自定义导出word表格的格式和内容,跨行跨列等操作
要将Java中的数据导出为Word表格并设置换行,可以使用Apache POI库来实现。具体步骤如下:
1. 创建表格并设置列数和行数
```
XWPFTable table = document.createTable(rowCount, colCount);
```
2. 遍历表格并设置单元格内容和样式
```
for (int i = 0; i < rowCount; i++) {
XWPFTableRow row = table.getRow(i);
for (int j = 0; j < colCount; j++) {
XWPFTableCell cell = row.getCell(j);
// 设置单元格内容
cell.setText(data[i][j]);
// 设置单元格样式
XWPFParagraph p = cell.getParagraphs().get(0);
XWPFRun r = p.createRun();
r.setText(data[i][j]);
r.addCarriageReturn(); // 设置换行
}
}
```
其中,`data`是要导出的数据数组。
3. 导出Word文档
```
FileOutputStream out = new FileOutputStream("output.docx");
document.write(out);
out.close();
document.close();
```
完整代码示例:
```
import java.io.FileOutputStream;
import org.apache.poi.xwpf.usermodel.*;
public class ExportWord {
public static void main(String[] args) throws Exception {
String[][] data = {{"A1", "B1", "C1"}, {"A2", "B2", "C2"}, {"A3", "B3", "C3"}};
int rowCount = data.length;
int colCount = data[0].length;
XWPFDocument document = new XWPFDocument();
XWPFTable table = document.createTable(rowCount, colCount);
for (int i = 0; i < rowCount; i++) {
XWPFTableRow row = table.getRow(i);
for (int j = 0; j < colCount; j++) {
XWPFTableCell cell = row.getCell(j);
// 设置单元格内容
cell.setText(data[i][j]);
// 设置单元格样式
XWPFParagraph p = cell.getParagraphs().get(0);
XWPFRun r = p.createRun();
r.setText(data[i][j]);
r.addCarriageReturn(); // 设置换行
}
}
FileOutputStream out = new FileOutputStream("output.docx");
document.write(out);
out.close();
document.close();
}
}
```
