使用Apache POI在Excel的下拉列表中添加值时出错

Question

我有这样的代码：

CellRangeAddressList addressListTax = new CellRangeAddressList(rowCount, rowCount, labelRowCnt, labelRowCnt);

DVConstraint dvConstraintTax = DVConstraint.createExplicitListConstraint(new String[]  { 

    "I0-Input Tax 0%", "I1-Input Tax 10% ", "I2-Input Tax 12%","IE-Input Tax Exempt",
    "J0-0% Input Tax,China ","J1-17% Input Tax,China ","J2-13% Input Tax,China  ",
    "J3-6% Input Tax,China","J4-4% Input Tax,China ","J5-3% Input Tax,China",
    "J6-7% Input Tax,China", "L1-5% Luxury Tax,China ", "O0-Zero-rated Sales ",
    "O1-Output Tax 10%  ","O2-Output Tax 12% ","OE-Output Tax Exempt ",
    "P0-Purchase Tax 0%  ","P1-Tax on Purchase 0%","P2-Tax on Purchases 5% ",
    "P3-Tax on Purchases 7%", "P4-Out of Scope purchase 0% ", "P5-Imported Purchase 0% ",
    "S0-Exempted Tax on Sales  ","S1-Tax on Sales 0% ","S2-Tax on Sales 5% ",
    "S3-7% GST  ","S3-Tax on Sales 7%","X0-0% Output Tax,China ","X0-China Output Tax 0%",
    "X1-17% Output Tax,China","X2-13% Output Tax,China"
});

HSSFDataValidation dataValidationTax = new HSSFDataValidation(addressListTax,dvConstraintTax);

dataValidationTax.setSuppressDropDownArrow(false);
sheet.addValidationData(dataValidationTax);

Linux中的这个抛出错误：

Answer 1

我会假设你实际上是在寻找问题的解决方案，而不是向你陈述显而易见的事情……

我想出的解决方法是将受约束项目的列表添加到第二个工作表，保护工作表，然后参考范围来提取项目:请参阅http://poi.apache.org/spreadsheet/quick-guide.html上关于“从电子表格单元格创建数据验证”的文档

我做了这个解决方案，将我的列表添加到第二个工作表中，然后保护工作表。不确定Excel版本中下拉大小/项目的限制是什么，但它适用于与您相似的列表大小/内容。

在poi3.7下工作得很好。
