Missing cell borders across pages

Aspose.Words Product Family

Hello, I use aspose word to save the doc as a PDF. When the table cell in the document spans pages, the border of this cell will be missing. How to deal with it?

@yjsdfsdf Could you please attach your source and output documents here for testing? we will check the issue and provide you more information.

Thank you, I solved it temporarily. Can I help handle another problem? It is to convert the DOC to PDF, and the title runs to the right side。

@yjsdfsdf Unfortunately, I cannot reproduce the problem using the latest 23.5 version of Aspose.Words for Java. Please try using the latest version.

Sorry, I I forgot to paste the code。

// Open document
Document doc = new Document(dataDir + "华泰柏瑞沪深300交易型开放式指数证券投资基金2021年年度报告.doc");
for (Table table:(Iterable<Table>)doc.getChildNodes(NodeType.TABLE, true))
{
    for (Row row:(Iterable<Row>)table.getChildNodes(NodeType.ROW, true))
    {
        for (Cell cell: (Iterable<Cell>)row.getChildNodes(NodeType.CELL, true))
        {
            cell.getCellFormat().getBorders().getBottom().setLineStyle(LineStyle.SINGLE);
            cell.getCellFormat().getBorders().getTop().setLineStyle(LineStyle.SINGLE);
        }
    }
}

Iterable<Cell> cells = doc.getChildNodes(NodeType.CELL, true);
LayoutCollector collector = new LayoutCollector(doc);
for (Cell cell:cells)
{
    if (collector.getNumPagesSpanned(cell) > 0)
    {
        cell.getParentRow().getFirstCell().getFirstParagraph().getParagraphFormat().setPageBreakBefore(true);
        collector.clear();
        doc.updatePageLayout();
    }
}

doc.save(dataDir + "finals地方.pdf");

@yjsdfsdf The problem occur because the table is floating and when content is moved document layout is changed. You can make the table inline to avoid such probems:

table.setTextWrapping(TextWrapping.NONE);

But the table contains a lot of empty rows underneath, which is why

@yjsdfsdf Yes, this is side effect of the proposed workaround. You can remove empty paragraphs to avoid this:

Iterable<Paragraph> paragraphs = doc.getChildNodes(NodeType.PARAGRAPH, true);
for (Paragraph p : paragraphs)
{
    if (IsEmptyParagraph(p) && IsEmptyParagraph(p.getNextSibling()))
    {
        p.remove();
    }
}

private static boolean IsEmptyParagraph(Node node) throws Exception
{
    if (node == null || node.getNodeType() != NodeType.PARAGRAPH)
        return false;
        
    Paragraph p = (Paragraph)node;
        
    // Consider paragraph as empty if it does not have text and shapes.
    return p.toString(SaveFormat.TEXT).trim().equals("") &&
            (p.getChildNodes(NodeType.SHAPE, true).getCount() == 0);
}

Run this code before processing tables. But note all changes to the document node structure affects the document layout. So there is no general solution for all documents.

I used the following code to convert doc to PDF, and only one table had missing edges.
can you help me? thank you

// Open document
Document doc = new Document(dataDir + "华泰柏瑞健康生活灵活配置混合型证券投资基金2022年年度报告-1.doc");
for (Table table:(Iterable<Table>)doc.getChildNodes(NodeType.TABLE, true))
{
    table.setTextWrapping(TextWrapping.NONE);
    for (Row row:(Iterable<Row>)table.getChildNodes(NodeType.ROW, true))
    {
        for (Cell cell: (Iterable<Cell>)row.getChildNodes(NodeType.CELL, true))
        {
            cell.getCellFormat().getBorders().getBottom().setLineStyle(LineStyle.SINGLE);
            cell.getCellFormat().getBorders().getTop().setLineStyle(LineStyle.SINGLE);
        }
    }
}

Iterable<Cell> cells = doc.getChildNodes(NodeType.CELL, true);
LayoutCollector collector = new LayoutCollector(doc);
for (Cell cell:cells)
{
    if (collector.getNumPagesSpanned(cell) > 0)
    {
        cell.getParentRow().getFirstCell().getFirstParagraph().getParagraphFormat().setPageBreakBefore(true);
        collector.clear();
        doc.updatePageLayout();
    }
}

doc.save(dataDir + "output.pdf");

@yjsdfsdf Please try to change order of calling Document.updatePageLayout and LayoutCollector.clear methods:

doc.updatePageLayout();
collector.clear();

It does not work, other tables will have problems, you can see the attached picture

@yjsdfsdf If the problem is the top border, you can set border around the whole table:

table.setBorders(LineStyle.SINGLE, 1, Color.BLACK);
