如何使用docx4j向表中添加多行

我有一个表,我需要为它添加多行,而不是你在图像中看到的变量。我正在使用docx4j。 table 我改变了这样的变量:

HashMap mappings = new HashMap();
VariablePrepare.prepare(template);
mappings.put("example", "example");
template.getMainDocumentPart().variableReplace(mappings);

VariableReplace不用于重复数据。

您可以使用OpenDoPE内容控件数据绑定:在表格行周围包装重复内容控件。

https://github.com/plutext/docx4j/blob/master/src/main/java/org/docx4j/model/datastorage/migration/FromVariableReplacement.java可能有助于从VariableReplace迁移到OpenDoPE。

这对我有用 - 但我的单词模板中没有列标题,所以要小心它们可能会破坏此功能。
只需正确填充HashMap,如果你正确设置了一切就可以开箱即用;)

这些是我用于替换的3个功能:

private void replaceTable(String[] placeholders, List<Map<String, String>> textToAdd, WordprocessingMLPackage template) throws Docx4JException, JAXBException {
    List<Object> tables = doc.getAllElementFromObject(template.getMainDocumentPart(), Tbl.class);
    Tbl tempTable = getTemplateTable(tables, placeholders[0]);
    List<Object> rows = doc.getAllElementFromObject(tempTable, Tr.class);
    if (rows.size() == 1) { //careful only tables with 1 row are considered here
        Tr templateRow = (Tr) rows.get(0);
        for (Map<String, String> replacements : textToAdd) {
            addRowToTable(tempTable, templateRow, replacements);
        }
        assert tempTable != null;
        tempTable.getContent().remove(templateRow);
    }
}

private void addRowToTable(Tbl reviewTable, Tr templateRow, Map<String, String> replacements) {
    Tr workingRow = (Tr) XmlUtils.deepCopy(templateRow);
    List<?> textElements = doc.getAllElementFromObject(workingRow, Text.class);
    for (Object object : textElements) {
        Text text = (Text) object;
        String replacementValue = (String) replacements.get(text.getValue());
        if (replacementValue != null)
            text.setValue(replacementValue);
    }
    reviewTable.getContent().add(workingRow);
}

private Tbl getTemplateTable(List<Object> tables, String templateKey) throws Docx4JException, JAXBException {
    for (Object tbl : tables) {
        List<?> textElements = doc.getAllElementFromObject(tbl, Text.class);
        for (Object text : textElements) {
            Text textElement = (Text) text;
            if (textElement.getValue() != null && textElement.getValue().equals(templateKey))
                return (Tbl) tbl;
        }
    }
    return null;
}

以下是大致如何将它用于您的示例:

ArrayList<Map<String, String>> list = new ArrayList<>();
//Create a loop here through all entries
Map<String, String> entry = new HashMap<>();
entry.put("${nrCrt}", "1");
list.add(entry);
//...
entry.put("${tva}", "55");
list.add(entry);
entry.put("${nrCrt}", "2");
list.add(entry);
//...

replaceTable(new String[]{"${nrCrt}"}, list, template);

我忘了提及:
doc只是一个帮助类,这是getAllElementFromObject

的实现
public List<Object> getAllElementFromObject(Object obj, Class<?> toSearch) {
    List<Object> result = new ArrayList<Object>();
    if (obj instanceof JAXBElement) obj = ((JAXBElement<?>) obj).getValue();

    if (obj.getClass().equals(toSearch))
        result.add(obj);
    else if (obj instanceof ContentAccessor) {
        List<?> children = ((ContentAccessor) obj).getContent();
        for (Object child : children) {
            result.addAll(getAllElementFromObject(child, toSearch));
        }
    }
    return result;
}
