Context

Controller Context – get_index_label()

...

return either a array with following fields or (for historical reasons) return a string with index/header description:

* @param  - tablename of model
* @paramindex_header - array like [$table.'.column1' , $table.'.column2', ..., 'foreigntable1.column1', 'foreigntable2.column1', ..., 'customcolumn']
* order in index_header is important and datatables will have the column order given here
* @parambsclass - defines a Bootstrap class for colering the Rows
* @paramheader - defines whats written in Breadcrumbs Header at Edit and Create Pages
* @paramedit - array like [$table.'.column1' => 'customfunction', 'foreigntable.column' => 'customfunction', 'customcolumn' => 'customfunction']
* customfunction will be called for every element in table.column, foreigntable.column or customcolumn
* CAREFUL customcolumn will not be sortable or searchable - to use them anyways use the disable_sortsearch key
* @parameager_loading array like [foreigntable1, foreigntable2, ...] - eager load foreign tables
* @paramorder_by array like ['0' => 'asc'] - order table by id in ascending order, ['1' => 'desc'] - order table after first column in descending order
* @paramdisable_sortsearch array like ['customcolumn' => 'false'] disables sorting & searching for the chosen column (e.g. when it is impossible) => prevent errors
