如何通过使用带有itext 7库的Cell来获取上述内容

How to get the content as above, by using Cell with itext 7 library

我使用 cell.setPadding（0f）; 但它没有帮助我按预期得到结果。

I used the cell.setPadding(0f); but it didn't helped me to get the results as expected.

推荐答案

您似乎忘记将要添加的内容的前导设置为 Cell 。我试图模仿您分享的屏幕截图：

It seems that you forgot to set the leading of the content you are adding to the Cell. I tried to mimic the screen shot you shared:

这是我以前使用的代码：

This is the code I used to do so:

public void createPdf(String dest) throws IOException {
    // step 1
    PdfDocument pdfDocument = new PdfDocument(new PdfWriter(dest));
    pdfDocument.setDefaultPageSize(PageSize.A4.rotate());
    // step 2
    Document document = new Document(pdfDocument);
    // step 3
    Table table = new Table(new float[]{ 50 , 50 });
    table.setWidthPercent(30);
    table.addCell(new Cell().setPadding(0).setTextAlignment(TextAlignment.CENTER)
            .add(new Paragraph("4.0").setMultipliedLeading(1.2f).setItalic()));
    table.addCell(new Cell().setPadding(0).setTextAlignment(TextAlignment.CENTER)
            .add(new Paragraph("0.14").setMultipliedLeading(1.2f).setItalic()));
    document.add(table);
    // step 4
    document.close();
}

在这种情况下，我使用了乘以的前导1.2F 。随意更改该值。

In this case, I used a multiplied leading of 1.2f. Feel free to change that value.

注意：非常烦人的是您无法在父级上设置级别的值（例如表，文档，...）。我已经创建了关于JIRA的功能请求，希望能够在下一个版本。

Note: it is very annoying that you can't set the value of the level on a parent (e.g. the table, the document,...). I have created a feature request on JIRA in the hope that this will be supported in the next version.
