使用 APACHE POI 在 Excel 中使用条件格式

Question

I have a problem using the SheetConditionalFormatting, just for testing if the cell contains particular string (in my case just "test") I run the following code:

    SheetConditionalFormatting sheetConditionalFormatting = excelSheet.getSheetConditionalFormatting();

    ConditionalFormattingRule rule = sheetConditionalFormatting.createConditionalFormattingRule(ComparisonOperator.EQUAL, "test");
    PatternFormatting fill1 = rule.createPatternFormatting();
    fill1.setFillBackgroundColor(IndexedColors.BLUE.index);
    fill1.setFillPattern(PatternFormatting.SOLID_FOREGROUND);

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

    sheetConditionalFormatting.addConditionalFormatting(regions, rule);

And I got message that 'test' does not exist in the workspace. This is my error from Console:

Exception in thread "main" org.apache.poi.ss.formula.FormulaParseException: Specified named range 'test' does not exist in the current workbook.

Answer 1

发现在createConditionalFormattingRule中引入的字符串必须是单元格坐标

ConditionalFormattingRule rule = sheetConditionalFormatting.createConditionalFormattingRule(ComparisonOperator.EQUAL, "B1");

Answer 2

To use a string as a comparison it need to be inclosed in quotes eg:

"""string"""
