No, it selects a sequence of numbers 1,2,3 up to the highest value of
@col in your document.

We could have equally written select=".": this is the current column
number

We're now selecting a sequence of numbers from 1,2,3 up to the highest
@row number in your document [I can't think why I did it this way round,
you want rows in the outer loop and columns in the inner loop, of
course]

We now select the cell with the particular row and column number, if
there is one, and output it. If there isn't one, we output nothing. If
there are two, <xsl:value-of> selects the first.

The logic is

for row from 1 to n
  <tr>
  for column from 1 to m
    <td>
    output cell[row, column]
    </td>
  end-for
  </tr>
end-for
