Usage  The template provides a standardised table header for a List of isotopes, as is used in each of the 118 Isotopes of <element> articles. Parameters allow for adjustment of the table header structure, references and table footnotes. This header does not change existing rows: values, isotope-specific footnotes, structure, nor split decay routes .  The parameters are  will do various settings, including appropriate natural abundance column headers  will add an inline reference(s) for any 2016 data update. E.g.,   will add multiple footnotes, mostly notational clarifications (like for "m", "SF"), and optional column headers like "Historical name"  The table is closed by adding .

Column and row variants  These header options are set by :  + Historic name column: opt-in by setting  (some 11 elements, )  + Excitation energy data, in eV: the isotope row has a 2nd row with mXx isotope opt-in by setting  (some 100 elements)  + [resonance width] wikilink added in header Half-life: opt-in by setting  (some 10 elements)  + Note column, free text: opt-in by setting   These columns are added per :  + Natural abundance (only traces in nature): opt-in   (10x, ) (list maintained here)  + Natural abundance 2 columns: abundance in nature, and range of variation:  opt-out  (24x, same list) and () (list maintained here)  Table footnotes |notes=histname, resonance, m, mass#, unc(), hl#, spin#, exen#, hl-nst, daughter-nst, daughter-st, spin(), var[] CD, EC, IT, SF, n, p The input order is not relevant. Sequence shown is the order of appearance in the header (so m lists first, spin() last).
