Assume that your table structure is like this

HTML

<table id="Table4">
        <tr>
            <td>1</td>
            <td>2</td>
            <td>3</td>
            <td>4</td>
        </tr>
    </table>

then you will have to code as below to assign the values to the respective text box, i would recommend you to use break point[^] and debugger [^]to play around with the object and properties getting in the loop, based on that you can customize your code which suits your need.

C#

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
       {
          HtmlElement table =  webBrowser1.Document.GetElementById("table4");
          var rows = table.GetElementsByTagName("tr");
          foreach (HtmlElement row in rows)
          {  int i = 0;
              foreach (HtmlElement cell in row.GetElementsByTagName("td"))
              {
                  i++;
                  string value = cell.InnerText;
                  if (i == 1)
                      textBox1.Text = value;
                  if (i == 2)
                      textBox2.Text = value;
                  if (i == 3)
                      textBox3.Text = value;
                  if (i == 4)
                      textBox4.Text = value;

              }
          }


       }

Since you knew the Id of the table, you can get the Table Element by using GetElementById instead of TagName

i use this and works fine

C#

var theElementCollectionChildNext2 = webBrowserwelcome.Document.GetElementsByTagName("a");
                      foreach (HtmlElement elChild in theElementCollectionChildNext2)
                      {

                          if (elChild.Id == "HyperLink4")
                          {
                              hyperlinkLabelControl1.Text = elChild.GetAttribute("href");
                          }

                          else if (elChild.Id == "HyperLink5")
                          {
                              hyperlinkLabelControl2.Text = elChild.GetAttribute("href");
                          }

                          else if (elChild.Id == "HyperLink6")
                          {
                              hyperlinkLabelControl3.Text = elChild.GetAttribute("href");
                          }
