In the test document, I try to force the paragraph in the table of contents to have ownership
“setKeepTogether” set to true.
Steps to reproduce the expected result:
1.Create some texts as with the Header (1-9) style set
2. Create tables with 1 row
3. Create the TOC in the table
Expectations: After updating TOC, the table stops cannot disappear.
code:
final Table tableContainer = builder.startTable();
final Cell cell = builder.insertCell();
cell.getCellFormat().setFitText(false);
// set width, height table etc ...
final String newStyleName = "CustomTOC".concat(String.valueOf(r.nextInt(2_000_000)));
Style appliedStyle = builder.getDocument().getStyles().add(StyleType.PARAGRAPH, newStyleName);
appliedStyle.getParagraphFormat().setKeepTogether(true);
builder.getParagraphFormat().setStyleName(newStyleName);
final FieldToc field = (FieldToc) builder.insertTableOfContents("\\o \\h \\z \\u");
field.setPreserveLineBreaks(true);
builder.endTable();

Explains:
The above code generates the document with the table of contents. It is enough to click “update field” and the characters separating the content of the paragraph from the numbering disappear.
From what I checked it is related to the lack of setting
“keep together” for the paragraph containing the TOC.
