我得到了现有项目的分配更新。以前的开发人员使用 jcom api 将数据导出到 Excel 工作表。但是 jcom api 不适用于 64 位系统。我决定更改代码并使用 apache poi api。我设法做了很多方法。我的问题是数组公式。我需要使用 apache poi 实现数组公式。这些公式发布在下面,任何帮助都会更加明显。提前谢谢各位。
公式:
String formula1 = "SUM(R[-2]C/1.200)";//net income calculation from gross income
String formula2 = "SUM(R[-1]C-R[1]C)";
String formula3 = "SUM(R[-" + Integer.toString(listTypeTotals.size()+1) + "]C:R[-2]C)";
我试图将该单元格设置为公式类型并将公式作为字符串传递。
setCellFormulaStyle(sheet, 4, i+2, formula2);
public static void setCellFormulaStyle(HSSFSheet sheet,int row, int column,String value)
{
HSSFRow temprow = null;
temprow =getRow_CreateRow(sheet, row);
temprow.createCell(column).setCellFormula(value);
}
public static HSSFRow getRow_CreateRow(HSSFSheet sheet,int row)
{
HSSFRow excelrow=null;
excelrow = sheet.getRow(row);
if(excelrow==null)
{
excelrow =sheet.createRow(row);
return excelrow;
}else
return excelrow;
}
我收到以下异常
