Willem Jan之所以会出现这种情况，是因为前三张表格中的一些单元格的最小宽度很大。表格不适合页面区域，因此其宽度超出预期。当我们减小显示宽度时，这种效果也存在于HTML中： 为避免出现这种情况，您可以选择以下选项之一： 更改输出文档页面大小或页面方向：
PdfDocument pdfDocument = new PdfDocument(new PdfWriter(new FileInfo(outFilename)));
pdfDocument.SetDefaultPageSize(PageSize.A3);
// pdfDocument.SetDefaultPageSize(PageSize.A4.Rotate());
HtmlConverter.ConvertToPdf(new FileStream(srcFilename, FileMode.Open), pdfDocument);
这是因为前三个表中某些单元格的最小宽度很大。表格不适合页面区域，因此其宽度超出预期。当我们减小显示宽度时，这种效果也存在于HTML中： 为避免出现这种情况，您可以选择以下选项之一： 更改输出文档页面大小或页面方向：

pdfDocument.SetDefaultPageSize(PageSize.A3);
// pdfDocument.SetDefaultPageSize(PageSize.A4.Rotate());
HtmlConverter.ConvertToPdf(new FileStream(srcFilename, FileMode.Open), pdfDocument);
前三个表中导致最小宽度问题的单元格包含单行文本，其文件路径包含许多字符。因此，另一个选项可以是按此字符拆分文本。您可以在Java上使用以下代码示例：
public static void main(String[] args) {
ConverterProperties cp = new ConverterProperties();
cp.setCssApplierFactory(new CustomCssApplierFactory());
HtmlConverter.convertToPdf(new File(srcFilename), new File(outFilename), cp);
}
private static class CustomCssApplierFactory implements ICssApplierFactory {
private ICssApplierFactory defaultCssApplierFactory = new DefaultCssApplierFactory();
@Override
public ICssApplier getCssApplier(IElementNode tag) {
ICssApplier defaultCssApplier = defaultCssApplierFactory.getCssApplier(tag);
return defaultCssApplier != null ? new CustomCssApplier(defaultCssApplier) : null;
}
}
private static class CustomCssApplier implements ICssApplier {
private final ICssApplier defaultCssApplier;
public CustomCssApplier(ICssApplier defaultCssApplier) {
this.defaultCssApplier = defaultCssApplier;
}
@Override
public void apply(ProcessorContext context, IStylesContainer stylesContainer, ITagWorker tagWorker) {
defaultCssApplier.apply(context, stylesContainer, tagWorker);
IPropertyContainer elementResult = tagWorker.getElementResult();
if (elementResult != null) {
setCustomSplitCharacter(elementResult);
} else if (tagWorker instanceof SpanTagWorker) {
// If current element is span, then set the custom split character to nested elements
for (IPropertyContainer ownLeafElement : ((SpanTagWorker) tagWorker).getOwnLeafElements()) {
setCustomSplitCharacter(ownLeafElement);
}
}
}
private void setCustomSplitCharacter(IPropertyContainer elementResult) {
// If Property.SPLIT_CHARACTERS was null then DefaultSplitCharacters class would be used during layout.
Object property = elementResult.getProperty(Property.SPLIT_CHARACTERS);

前三个表中导致最小宽度问题的单元格包含单行文本，其文件路径包含许多字符。因此，另一个选项可以是按此字符拆分文本。您可以在Java上使用以下代码示例：
public static void main(String[] args) {
ConverterProperties cp = new ConverterProperties();
cp.setCssApplierFactory(new CustomCssApplierFactory());
HtmlConverter.convertToPdf(new File(srcFilename), new File(outFilename), cp);
}
private static class CustomCssApplierFactory implements ICssApplierFactory {
private ICssApplierFactory defaultCssApplierFactory = new DefaultCssApplierFactory();
@Override
public ICssApplier getCssApplier(IElementNode tag) {
ICssApplier defaultCssApplier = defaultCssApplierFactory.getCssApplier(tag);
return defaultCssApplier != null ? new CustomCssApplier(defaultCssApplier) : null;
}
}
private static class CustomCssApplier implements ICssApplier {
private final ICssApplier defaultCssApplier;
public CustomCssApplier(ICssApplier defaultCssApplier) {
this.defaultCssApplier = defaultCssApplier;
}
@Override
public void apply(ProcessorContext context, IStylesContainer stylesContainer, ITagWorker tagWorker) {
defaultCssApplier.apply(context, stylesContainer, tagWorker);
IPropertyContainer elementResult = tagWorker.getElementResult();
if (elementResult != null) {
setCustomSplitCharacter(elementResult);
} else if (tagWorker instanceof SpanTagWorker) {
// If current element is span, then set the custom split character to nested elements
for (IPropertyContainer ownLeafElement : ((SpanTagWorker) tagWorker).getOwnLeafElements()) {
setCustomSplitCharacter(ownLeafElement);
}
}
}
private void setCustomSplitCharacter(IPropertyContainer elementResult) {
// If Property.SPLIT_CHARACTERS was null then DefaultSplitCharacters class would be used during layout.
Object property = elementResult.getProperty(Property.SPLIT_CHARACTERS);
// BreakAllSplitCharacters and KeepAllSplitCharacters instances can be set
// if CSS word-break property was applied.
if (!(property instanceof BreakAllSplitCharacters)) {
elementResult.setProperty(Property.SPLIT_CHARACTERS, new CustomSlashSplitCharacters());
}
}
}
private static class CustomSlashSplitCharacters extends DefaultSplitCharacters {
private static final String SPLIT_CHARACTER = "\\";
@Override
public boolean isSplitCharacter(GlyphLine text, int glyphPos) {
Glyph glyph = text.get(glyphPos);
return glyph.hasValidUnicode() && SPLIT_CHARACTER.equals(glyph.getUnicodeString())
|| super.isSplitCharacter(text, glyphPos);
}
}
您可能希望从HTML中删除单个列宽，然后为表行的第一个子行添加一些CSS以使其不换行。类似这样的事情，我对HTML/CSS-tr td:first child{white space:nowrap；}不太了解。为了简化复制，您可以附加您试图转换的原始最小化HTML+CSS吗？@Ash:HTML似乎很好。我也尝试了css代码，但结果是一样的。完成后，请参阅修改后的帖子。您可能希望从HTML中删除单个列宽，然后为表行的第一个子行添加一些CSS以不换行。类似这样的事情，我对HTML/CSS-tr td:first child{white space:nowrap；}不太了解。为了简化复制，您可以附加您试图转换的原始最小化HTML+CSS吗？@Ash:HTML似乎很好。我也尝试了css代码，但结果是一样的。完成后，查看修改后的帖子。我使用了固定的像素宽度，而不是百分比。这是迄今为止最好的解决办法。正在创建不是解决方案的单个表：-我用固定的像素宽度代替了百分比。这是迄今为止最好的解决办法。正在创建不是解决方案的单个表：-虽然我不懂Java，但它可能对其他人有帮助。虽然我不懂Java，但它可能对其他人有帮助。
