具有公式的Apache POI颜色单元格

Question

我想在java中用Apache POI创建一个excel,我必须在单元格中插入一个公式:A3 = B3 + C3.

是否可以在A3中插入另一个公式,如果其值> 0,则为单元格着色？

我使用Apache POI 2.5.1

Answer 1

您将需要条件格式.

从这份文件:

 // Define a Conditional Formatting rule, which triggers formatting
 // when cell's value is greater or equal than 100.0 and
 // applies patternFormatting defined below.
 HSSFConditionalFormattingRule rule = sheet.createConditionalFormattingRule(
     ComparisonOperator.GE, 
     "100.0", // 1st formula 
     null     // 2nd formula is not used for comparison operator GE
 );

 // Create pattern with red background
 HSSFPatternFormatting patternFmt = rule.cretePatternFormatting();
 patternFormatting.setFillBackgroundColor(HSSFColor.RED.index);

 // Define a region containing first column
 Region [] regions =
 {
     new Region(1,(short)1,-1,(short)1)
 };

 // Apply Conditional Formatting rule defined above to the regions  
 sheet.addConditionalFormatting(regions, rule);

这会创建一个红色背景的单元格,值> = 100.这几乎是你想要的:-)
