Wait, the user specified "14 columns". Let me check that. The periodic table is usually 18 columns when including the transition metals and the f-block elements in their correct positions. If the 14 columns refer to a specific section, maybe the f-block is being emphasized here. But how does that tie into quantum numbers? The quantum numbers (n, l, m_l, m_s) define the electron configuration, so perhaps the table includes quantum numbers for each element's outermost electrons or their electron configurations.
