                ASPOSE_LICENSE.setLicense(stream);

Cause

The issue you’re encountering with the Table of Contents (TOC) width not matching the merged document’s width is likely due to differences in the page setup or margins between the original documents and the merged document. When merging documents, the TOC may not automatically adjust to the new document’s layout.

Solution

To ensure the TOC width aligns with the merged document, adjust the page setup and margins before inserting the TOC. Follow these steps:

  1. Set Page Setup: Ensure that the page setup (size, margins) of the merged document matches that of the source documents.
  2. Update TOC Field: After merging the documents, update the TOC field to reflect the correct layout.

Code

Here’s a modified version of your merging code that includes setting the page setup for the merged document:

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// Set page setup for the merged document
PageSetup pageSetup = doc.getFirstSection().getPageSetup();
pageSetup.setPaperSize(PaperSize.A4);
pageSetup.setTopMargin(72);
pageSetup.setBottomMargin(72);
pageSetup.setLeftMargin(72);
pageSetup.setRightMargin(72);

// Insert TOC
builder.writeln("Table of Contents");
FieldToc fieldToc = (FieldToc) builder.insertField(FieldType.FIELD_TOC, true);
fieldToc.setEntryLevelRange("1-3");
fieldToc.setInsertHyperlinks(true);

// Merge documents
names.forEach((fileName, tocTitle) -> {
    try {
        Document src = new Document(prefixPath + File.separator + fileName, loadOptions);
        doc.appendDocument(src, ImportFormatMode.KEEP_SOURCE_FORMATTING);
    } catch (Exception e) {
        e.printStackTrace();
    }
});

// Update TOC
doc.updateFields();
doc.save(savePath, SaveFormat.DOCX);

Next Steps

  1. Run the modified code to merge your documents.
  2. Check the TOC width in the merged document.
  3. If the issue persists, verify the individual document settings before merging.

Please let me know if you need further assistance!

需要我的是插入toc模式，而不是靠doc.updateFields();刷新生成的
