Apache POI未在Excel中為每一列呈現輸出
[英]Apache POI not rendering output in excel for every column
問題描述
我正在使用apache POI從數據庫讀取數據並渲染為excel。 我使用了Oracle數據庫。 我在excel中的預期輸出是所需的輸出
在此員工名稱為Devendra Singh和Yuvraj Verma。 在它們下面是它們各自的標記，編號為A1359和A1539。 R，W，FH，OTR，OTW，OTFH是每個員工的生產值。
使用System.out.print時，代碼顯示正確的位置，但不在Excel工作表中顯示。 也沒有例外。
//method to create cells
private static void createCell(XSSFWorkbook wb, XSSFRow row, short column, short halign, short valign,Object value) {
System.out.println("Creating row #"+row.getRowNum() + " Colm# "+column+" value "+value);
XSSFCell cell = row.createCell(column);
cell.setCellValue(value.toString());
CellStyle cellStyle = wb.createCellStyle();
if(column == 1) {
XSSFDataFormat df = wb.createDataFormat();
cellStyle.setDataFormat(df.getFormat("d mmm yy"));
}
cellStyle.setAlignment(halign);
cellStyle.setVerticalAlignment(valign);
cell.setCellStyle(cellStyle);
}
在System.out.println（）中獲取輸出為

你不應該打電話
row.setRowNum(1);
要么
spreadsheet.createRow
在這種循環中。 第一次調用沒有意義，第二次調用將覆蓋您在上一個循環迭代中已經創建的行。 取而代之的是，在循環之前創建行，然后使用spreadsheet.getRow .getRow在循環內部檢索它們。
使用Java，Apache POI在每3列之后在Excel中創建列標題
