Reply To: Mendeleev’s Table
Since the text mentions "chart" and "pattern" you should retain the print layout, as four columns of 14 rows. Use dot 5s to fill in the empty entries, using the full width of each column. (Column 4 has no empty entries.) Use the full cell for the question mark. You can adapt the wide table as either a foldout or divide it vertically. A TN can explain the smaller numbers after the (unspaced) commas.
