improvement(data-table): add cell formatters & custom tabular array option

[theiliad]

WIP

Here's what I'm testing with so far

{
	dataTable: {
		headingCellsFormatter: cell => Math.random().toFixed(2),
		dataCellsFormatter: cell => parseInt(Math.random() * 100 as any),
		// tabularArray: [["1", "2", "3"], [5235, 213123, 325], [214, 3256, 6346]]
	}
}
