在Java中使用Jsoup将HTML表格解析为JSON

String url = "http://example.com/table.html";
Document doc = Jsoup.connect(url).get();

Elements tables = doc.select("table");

for (Element table : tables) {
    Elements rows = table.select("tr");
    for (Element row : rows) {
        Elements columns = row.select("td");
        // 解析每个列的内容并构建JSON对象
    }
}

JsonObject json = new JsonObject();
for (Element table : tables) {
    Elements rows = table.select("tr");
    for (Element row : rows) {
        Elements columns = row.select("td");
        for (int i = 0; i < columns.size(); i++) {
            String columnName = "column" + i;
            String columnValue = columns.get(i).text();
            json.addProperty(columnName, columnValue);
        }
    }
}

String jsonString = json.toString();
