NTSH
Nothing To See Here
Ntsh (Number Table Sorting, Hidden) generates a hidden sort key that allows numbers to sort correctly when a column of a sortable table needs to be sorted alphabetically. This template is a hidden version of {{Number table sorting}}. See Help:Sorting#Sorting with a hidden key. It can be used to prefix non-numeric entries; for example, using {{ntsh|0}}None will cause "None" to be sorted as if it had a numeric value of zero.
