Java 使用单元格公式ApachePOI创建新列
我正在与ApachePOI合作,我遇到了一个问题,比如使用两列除法添加新列,还希望获得百分比% 这是我的意见 请求输出 这是java代码Java 使用单元格公式ApachePOI创建新列,java,apache-poi,Java,Apache Poi,我正在与ApachePOI合作,我遇到了一个问题,比如使用两列除法添加新列,还希望获得百分比% 这是我的意见 请求输出 这是java代码 public class ApacheCreatePivotTab { public static void main(String[] args) throws Exception { XSSFWorkbook wb = new XSSFWorkbook(); XSSFSheet sheet = wb.cre

XSSFSheet sheet = wb.createSheet();
//Create some data to build the pivot table on
setCellData(sheet);

public static void setCellData(XSSFSheet sheet)
{
Row row1 = sheet.createRow(0);
// Create a cell and put a value in it.
Cell cell11 = row1.createCell(0);
cell11.setCellValue("Names");
Cell cell12 = row1.createCell(1);
cell12.setCellValue("utilization_pct");
Row row2 = sheet.createRow(1);
// Create a cell and put a value in it.
Cell cell21 = row2.createCell(0);
cell21.setCellValue("Michal");
Cell cell22 = row2.createCell(1);
cell22.setCellValue("6772.00902935");
Row row3 = sheet.createRow(2);
// Create a cell and put a value in it.
Cell cell31 = row3.createCell(0);
cell31.setCellValue("Michal");
Cell cell32 = row3.createCell(1);
cell32.setCellValue("6118.1434599");
Row row4 = sheet.createRow(3);
// Create a cell and put a value in it.
Cell cell41 = row4.createCell(0);
cell41.setCellValue("Michal");
Cell cell42 = row4.createCell(1);
cell42.setCellValue("5000");
Row row5 = sheet.createRow(4);
// Create a cell and put a value in it.
Cell cell51 = row5.createCell(0);
cell51.setCellValue("Michal");
Cell cell52 = row5.createCell(1);
cell52.setCellValue("5279.50310559");
Row row6 = sheet.createRow(5);
// Create a cell and put a value in it.
Cell cell61 = row6.createCell(0);
cell61.setCellValue("Henry");
Cell cell62 = row6.createCell(1);
cell62.setCellValue("6170.8860759");
}
}
这段代码给了我一张工作表,我在上面执行了一个操作,将在其中添加第三列以添加第三列
Row row1 = sheet.createRow(0);
// Create a cell and put a value in it.
Cell cell11 = row1.createCell(0);
cell11.setCellValue("Names");
Cell cell12 = row1.createCell(1);
cell12.setCellValue("utilization_pct");
Cell cell13 = row1.createCell(2); // create third column
cell13.setCellValue("After_div and adding %");
将单元格格式更改为数字的步骤
Row row4 = sheet.createRow(3);
// Create a cell and put a value in it.
Cell cell41 = row4.createCell(0);
cell41.setCellValue("Michal");
Cell cell42 = row4.createCell(1);
cell42.setCellValue("5000");
Cell cell43 = row4.createCell(2);
HSSFCellStyle styleForNumeric = wb.createCellStyle();
styleForNumeric.setDataFormat(HSSFDataFormat.getBuiltinFormat("0.00")); // format cell to numeric
cell43.setCellStyle(styleForNumeric);
cell43.setCellValue("50.00");
只需将其四舍五入到2个十进制数字。谢谢,但我想首先使用java中的apache poi库执行单元格操作,我如何在java中执行此操作?您想创建新列吗?是的,必须在新列中添加此内容我不完全理解您的问题,您想要第三列,对吗?为什么不使用新的单元实例创建它,并在其中添加值呢
