当其中一列仅包含unicode数字时，无法导出数据表

Answer 1

尝试设置

setStronglyTypedCells(false);

，这不会尝试为 Excel 翻译数字。

public class CustomizedDocumentsView implements Serializable {
    private ExcelOptions excelOpt;

    @PostConstruct
    public void init() {
        excelOpt = new ExcelOptions();
        excelOpt.setStronglyTypedCells(false);
    }
    public ExcelOptions getExcelOpt() {
        return excelOpt;
    }
}

<h:commandButton value="Export as XLS">
    <p:dataExporter type="xls" target="tableId" fileName="cars" options="#{customizedDocumentsView.excelOpt}"/>
</h:commandButton>
