PrimeNG - Filter over an array of strings in datatable

Question

I want to filter a plain array of strings which is presented through a p-table. I know how to apply filtering and custom filtering in a list of objects through various ways, using their column properties but I have literally found no example for filtering into a list of plain strings

<p-table #table [value]="answers"> 
    ......
</p-table>

where answers is a list of strings

public answers: string[] = [];

I have thought that convert my answers object from array of strings into an array of single string property object as a solution, but I am wondering whether there is any way to keep it simple as that
