如何在C#中从HtmlTable中提取数据并排成一行？

using HtmlAgilityPack;

HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(html); // html为包含HtmlTable的字符串

HtmlNode tableNode = doc.DocumentNode.SelectSingleNode("//table");

string rowData = "";
foreach (HtmlNode row in tableNode.SelectNodes("tr"))
{
    foreach (HtmlNode cell in row.SelectNodes("th|td"))
    {
        rowData += cell.InnerText + " ";
    }
}

rowData = rowData.Trim(); // 去除首尾空格
