This currently uses the LINQ methods .First() and .Skip() both are easy to recreate if you need to use this on .Net 2.0

//even cooler as an extension method
static IEnumerable<string> ReadAsLines(string filename)
{
    using (var reader = new StreamReader(filename))
        while (!reader.EndOfStream)
            yield return reader.ReadLine();
}

static void Main()
{
    var filename = "tabfile.txt";
    var reader = ReadAsLines(filename);

    var data = new DataTable();

    //this assume the first record is filled with the column names
    var headers = reader.First().Split('');
    foreach (var header in headers)
        data.Columns.Add(header);

    var records = reader.Skip(1);
    foreach (var record in records)
        data.Rows.Add(record.Split(''));
}
