Apache poi中心对齐

Question

我想对齐文字.但是,文本未对齐.

Cell lastCell = lastCell = row.createCell(cellNumber++);
if (value != null) {
    lastCell.setCellValue(value);
}
CellStyle cellStyle = lastCell.getCellStyle();
cellStyle.setAlignment(CellStyle.ALIGN_RIGHT);
lastCell.setCellStyle(cellStyle);

Answer 1

您可以替换：

cellStyle.setAlignment(CellStyle.ALIGN_RIGHT);

与：

cellStyle.setAlignment(HorizontalAlignment.RIGHT);

Answer 2

    lastCell = row.createCell(cellNumber++);

    CellStyle cellStyle = row.getSheet().getWorkbook().createCellStyle();
    cellStyle.setAlignment(CellStyle.ALIGN_RIGHT);
    lastCell.setCellStyle(cellStyle);

    if (number != null) {
        lastCell.setCellValue(number);
    }

从工作簿创建新的单元格样式.

    CellStyle cellStyle = row.getSheet().getWorkbook().createCellStyle();
