我尝试使用JAVA POI读取和使用Xslx文件,编辑并保存。但是当我更改第0行(Header)上的任何单元格值时,输出文件会被破坏。
Excel可以通过修复表来自/xl/tables/table.xm恢复文件。
FileInputStream file = new FileInputStream("inventorywithbin431.xlsx");
XSSFWorkbook workbook = (XSSFWorkbook) WorkbookFactory.create(file);
XSSFSheet rawdata = workbook.getSheetAt(0);
String[] headers = new String[] { "ItemCodeNoFRU","Company","ItemCode","ItemName","ItemGroup","PartNumber","Warehouse","Segment","Bin","WareHouseQty","OnOrder","IsCommited","BinQty","Cost","BinExtCost"};
//Set Header
for(int i=0;i<14;i++)
rawdata.getRow(0).getCell(i).setCellValue(headers[i]);
file.close();
//write changes
try (
FileOutputStream output_file = new FileOutputStream("inventorywithbin431.xlsx")) {
workbook.write(output_file);
output_file.flush();
output_file.close();
}
