您好!关于您的问题,可以使用Java中的POI库来操作Excel,并使用Cell的setCellStyle方法来设置每一列的位置格式。具体步骤如下:
1. 创建Excel工作簿对象并打开Excel文件:
```java
Workbook workbook = new XSSFWorkbook();
Sheet sheet = workbook.createSheet("Sheet1");
```
2. 创建单元格样式对象,并设置样式:
```java
CellStyle style = workbook.createCellStyle();
style.setAlignment(HorizontalAlignment.CENTER); // 设置水平居中对齐
style.setVerticalAlignment(VerticalAlignment.CENTER); // 设置垂直居中对齐
```
3. 遍历每一列并设置样式:
```java
for (int i = 0; i < columnCount; i++) {
CellStyle columnStyle = workbook.createCellStyle();
// 设置样式
sheet.setColumnWidth(i, 5000); // 设置列宽
for (int j = 0; j < rowCount; j++) {
// 创建单元格并设置值和样式
Cell cell = sheet.getRow(j).getCell(i);
cell.setCellValue(data[j][i]);
cell.setCellStyle(columnStyle);
}
}
```
其中,columnCount表示列数,rowCount表示行数,data表示Excel数据。
希望这能解决您的问题!
