Declare variable in custom template in Angular 2

Question

How can I declare variable that isn't coming from parent component? In this example rowData comes from p-column but I need to declare another variable.

<p-column *ngFor="let h of header">
    <template let-ms="rowData" pTemplate="body" let-m="getMetricByName(ms.metrics, h)">
                {{m.name}} //for example
    </template>
</p-column>

Answer 1

There is currently no way to declare variables in the template.
