One way to do it is:

var lines = File.ReadAllLines("input.txt");
if (lines.Count() > 0)
{
    foreach (var columnName in lines.FirstOrDefault()
        .Split(new[] { ' ' }, StringSplitOptions.RemoveEmptyEntries))
    {
        dataGridView1.Columns.Add(columnName, columnName);
    }
    foreach (var cellValues in lines.Skip(1))
    {
        var cellArray = cellValues
            .Split(new[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);
        if (cellArray.Length == dataGridView1.Columns.Count)
            dataGridView1.Rows.Add(cellArray);
    }
}

Of course, this works for the sample input file that you provided. Any variation to that format would require further validation and an increase in code complexity.
