使用iText在PDF中向表格添加行 [英] Adding a row to a table in PDF using iText

问题描述

我在这段代码中得到的是一个有8列3行的表.

What I'm getting in this code is a table with 8 columns and 3 rows.

我应该怎么做才能得到2行?并且三行中的第一列为空，但其余单元格都用"hi"填充.

What should I do to get just 2 rows? And the 1st column in the 3 rows are empty, but the remaining cells are filled with "hi".

PdfPTable table = new PdfPTable(8);

PdfPCell cell;

cell = new PdfPCell();
cell.setRowspan(2);
table.addCell(cell);

for(int aw=0;aw<8;aw++){
    table.addCell("hi");
}

推荐答案

尝试一下:

PdfPTable table = new PdfPTable(8);

    PdfPCell cell;
    for(int aw=0;aw<8;aw++)
    {
        cell = new PdfPCell(new Paragraph("hi"));
        table.addCell(cell );
    }

    // Step 1
    Document document = new Document();
    // step 2
    PdfWriter.getInstance(document, new FileOutputStream(filename));
    // step 3
    document.open();
    // step 4

PdfPTable table = new PdfPTable(8);
   for(int aw=0;aw<16 ; aw++){
        table.addCell("hi");
    }



    // Step 5
    document.add(table);
    // step 6
    document.close();

有关完整的示例代码和 SimpleTable ./itextpdf.com/sites/default/files/simple_table.pdf"rel =" nofollow noreferrer>生成PDF :

See SimpleTable for the full sample code and the resulting PDF:

如您在屏幕快照中所见，该表有8列和2行(按预期).

As you can see in the screen shot, the table has 8 columns and 2 rows (as expected).

在阅读原始问题时，我看到第一列有一个带有colspan 2的单元格.考虑到这一点，这只是一个很小的改变:

Reading the original question, I see that the first column has a cell with colspan 2. It's only a small change to take this into account:

PdfPTable table = new PdfPTable(8);
PdfPCell cell = new PdfPCell(new Phrase("hi"));
cell.setRowspan(2);
table.addCell(cell);
for(int aw = 0; aw < 14; aw++){
    table.addCell("hi");
}

现在结果如下:

再次有8列和两行，但是现在第一列中的单元格跨越了两行.

Again 8 columns and two rows, but now the cell in the first column spans two rows.
