/**
|
|
* When sorting values in a DataTable you might want to sort any 'novalue'
|
|
* pattern as max or min value in a column (e.g. '-' treat as -1000 or 1000).
|
|
*
|
|
* This is very useful if You want to sort incomplete data, there is no
|
|
* data available for each entry in a column (e.g. Recovered for covid-19).
|
|
*
|
|
* If You do not have data, You can set the 'novalue' pattern to '-' or
|
|
* any other pattern and set exact column to treat this 'novalue' pattern
|
|
* as the max value (sethigh) or the min value (setlow).
|
|
*
|
|
* @name novalue.js
|
|
* @summary Sort any "novalue" pattern as max or min (e.g. '-' treat as -1000 or 1000).

* @example
|
|
*
|
|
* gTable = $('#covid-table').DataTable({
|
|
* "orderClasses": true,
|
|
* "responsive": true,
|
|
* "columnDefs": [ { "type": "sethigh", "targets": [2, ,3, 4, 7, 8] },
|
|
* { "type": "setlow", "targets": [5, 6] } ]
|
|
* });
|
|
*
|
|
* To change order later:
|
|
*
|
|
* gTable.order([8, 'asc'],[6, 'desc']).draw();
|
|
*
|
|
* Keep in mind there must be "desc" in this case not "dsc".
