server example - _.slice start end

[MichaelChambers]

In server.component.ts loadData, you have
this.data = _.slice(this.data, this.activePage, this.activePage + this.rowsOnPage);

For me, that didn't work correctlly as the display was only increasing one row at a time. I have:

	const start :number = (this.activePage - 1) * this.rowsOnPage,
		end :number = _.min([start + this.rowsOnPage, this.data.length]);
	this.data = _.slice(this.data, start, end);
