Ntsh (Number Table Sorting, Hidden) is the hidden version of Nts, for correctly sorting tables by their numeric columns. It does the same as Nts, except that it doesn't display anything visible. It can be used to prefix non-numeric entries; for example, you can write {{ntsh|0}}None to have the entry to the end of the table when sorting numerically using Nts.

To use Help:Sorting and have it function correctly, numbers must be entered without thousands separators. To enable the display of thousands separators, this template automatically creates the hidden <span style="display:none">&&&&&&&123456789.&&1230</span> before the actual displayed number. It forces the sorting routine to use text sort on the hidden segment, which functions correctly due to the preceding ampersands (currently till 16 digits before, and 6 digits after the decimal separator).

Only one: a real number without thousand separators.

{{Ntsh|123456789.00123}}

Output sent to table

 <span style="display:none">&&&&&&&123456789.&&1230</span>
