=>First assign the "ID" field to table.
=>Call javascript fucntion before saving data to database to insert table rows into hiddenfields.
=>Start from second row of table,find each control in row, insert value of this control into hiddenfield separated by special character.
=>Once one row is insert into hiddenfield again insert another special character which indicates starting of the another row.

thus all the values will be insert into one hiddenfiled ,it will also help you separate each row,each value from heddenfield to insert into database.

JavaScript

function  FillHidn()
    {
     var tbl=document.getElementById('myTable');//ID of table which you have given.
     var hiddenField=document.getElementById('<%=myHidden.ClientID %>');//hiddenfield.
     var result='';
     if(tbl.rows.length>1)
     {
      for(var RowCnt=1;RowCnt1)
     {
      result=result.substring(1);
     }
     hiddenField.value=result;
     return true;
    }

<asp:HiddenField ID="myHidden" runat="server" />
<asp:Button ID="Button1" runat="server" Text="save" OnClientClick="return FillHidn();" OnClick="Button1_Click" />

C#

protected void Button1_Click(object sender, EventArgs e)
    {
        if (myHidden.Value.Length &gt; 0)
        {
             string[] RowArr=myHidden.Value.Split('^');
             foreach (string obj in RowArr)
             {
                 string[] Cntrls = obj.Split('~');
                 //You can use this code to insert the rows into databse.
                 //Cntrls[0] First Cloumn of the table
                 //Cntrls[1] Second Cloumn of the table
                 //Cntrls[2] Third Cloumn of the table
             }
        }
    }
