java - 如何使用java定义Excel工作表的动态单元格范围？

Question

这是我的代码:

SheetConditionalFormatting sheetCF = sheet.getSheetConditionalFormatting();
ConditionalFormattingRule rule = sheetCF.createConditionalFormattingRule( "MOD(ROW() - 1, 1) = 0");
PatternFormatting fill = rule.createPatternFormatting();
style.setFillForegroundColor(IndexedColors.BLUE.index);
style.setFillPattern(CellStyle.SOLID_FOREGROUND);

FontFormatting ffRed = rule.createFontFormatting();
ffRed.setFontColorIndex(IndexedColors.WHITE.index);

CellRangeAddress[] regions = {  CellRangeAddress.valueOf("A1:ZZ1") };

sheetCF.addConditionalFormatting(regions,rule);

ConditionalFormattingRule rule1 = sheetCF.createConditionalFormattingRule(
                        "MOD(ROW() - 1, 2) = 0");

PatternFormatting fill1 = rule1.createPatternFormatting();
fill1.setFillBackgroundColor(IndexedColors.PALE_BLUE.index);
fill1.setFillPattern(PatternFormatting.SOLID_FOREGROUND);

CellRangeAddress[] regions1 = {  CellRangeAddress.valueOf("A2:ZZ8304") };

sheetCF.addConditionalFormatting(regions1,rule1);

在 CellRangeAddress.values 中我给出了静态值。但我希望它是动态的。也就是说，只要有数据存在，它就应该动态变化。如何解决这个问题？我提到了define dynamic cell range但没有成功。

你可以这样尝试

String name = CellReference.convertNumToColString(cell.getColumnIndex());
    String location = "$" + name + "$" + cell.getRowIndex() + ":$" + name + "$" + (cell.getRowIndex() + 1);

    CellRangeAddress[] regions = { CellRangeAddress.valueOf(location) };
