我有一个Excel文件,其中有5列包含很少的合并单元格,空白单元格,日期和其他文本信息(普通的Excel文件)。
我正在使用Java中的POI API读取此文件。我可以使用iText jar将文件转换为pdf表。
但是,整个格式不会复制到pdf中。 (例如,合并的单元格进入一列,其他格式或设置都消失了)。
创建一个简单的pdf表。
如何保留与excel相同的格式? (我想要PDF格式的excel表格的精确副本)
以下是我正在使用的代码
//First we read the Excel file in binary format into FileInputStream
FileInputStream input_document = new FileInputStream(new File("K:\\DCIN_TER\\DCIN_EPU2\\CIRCUIT FROM BRANCH\\RAINBOW ORDERS\\" + SONo.trim() + "\\" + SONo.trim() + " - Checklist.xls"));
// Read workbook into HSSFWorkbook
HSSFWorkbook my_xls_workbook = new HSSFWorkbook(input_document);
// Read worksheet into HSSFSheet
HSSFSheet my_worksheet = my_xls_workbook.getSheetAt(0);
// To iterate over the rows
Iterator<Row> rowIterator = my_worksheet.iterator();
//We will create output PDF document objects at this point
com.itextpdf.text.Document iText_xls_2_pdf = new com.itextpdf.text.Document();
PdfWriter.getInstance(iText_xls_2_pdf, new FileOutputStream("K:\\DCIN_TER\\DCIN_EPU2\\CIRCUIT FROM BRANCH\\RAINBOW ORDERS\\" + SONo.trim() + "\\" + SONo.trim() + " - Checklist.pdf"));
iText_xls_2_pdf.open();
//we have 5 columns in the Excel sheet, so we create a PDF table with 5 columns; Note: There are ways to make this dynamic in nature, if you want to.
PdfPTable my_table = new PdfPTable(5);
//We will use the object below to dynamically add new data to the table
PdfPCell table_cell;
//Loop through rows.
while(rowIterator.hasNext())
{
Row rowi = rowIterator.next();
Iterator<Cell> cellIterator = rowi.cellIterator();
while(cellIterator.hasNext())
{
Cell celli = cellIterator.next(); //Fetch CELL
switch(celli.getCellType())
{
//Identify CELL type you need to add more code here based on your requirement / transformations
case Cell.CELL_TYPE_STRING:
//Push the data from Excel to PDF Cell
table_cell = new PdfPCell(new Phrase(celli.getStringCellValue()));
//move the code below to suit to your needs
my_table.addCell(table_cell);
break;
case Cell.CELL_TYPE_NUMERIC:
//Push the data from Excel to PDF Cell
table_cell = new PdfPCell(new Phrase("" + celli.getNumericCellValue()));
//move the code below to suit to your needs
my_table.addCell(table_cell);
break;
}
//next line
}
}
//Finally add the table to PDF document
iText_xls_2_pdf.add(my_table);
iText_xls_2_pdf.close();
//we created our pdf file..
input_document.close(); //close xls
