如何使用java为Excel工作表定义动态单元格范围? [英] How to define dynamic cell range for Excel sheet using java?

问题描述

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，它就应该动态地获取范围.如何解决这个问题?我提到了定义动态单元格范围，但没有奏效.

Inside CellRangeAddress.values I gave static value. But I wanted it to be dynamic. That is wherever there's data present it should take range dynamically. How to resolve this issue? I referred to define dynamic cell range but it didn't work.

推荐答案

你可以这样试试

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

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