Monitor your console log when tapping a row.

Getting Started

First we need a set of source data. This can start as either an array of objects, or an array of arrays. For this example we'll use the former.

typescript 
const sourceData = [
	{ position: 1, name: 'Hydrogen', weight: 1.0079, symbol: 'H' },
	{ position: 2, name: 'Helium', weight: 4.0026, symbol: 'He' },
	{ position: 3, name: 'Lithium', weight: 6.941, symbol: 'Li' },
	{ position: 4, name: 'Beryllium', weight: 9.0122, symbol: 'Be' },
	{ position: 5, name: 'Boron', weight: 10.811, symbol: 'B' },
];

Create a TableSource object that houses all of our table information. Note we're using the tableMapperValues() method to prune and map our data between the body and meta values. We cover the use of this method in the Table Utilities section below.

typescript 
const tableSimple: TableSource = {
	// A list of heading labels.
	head: ['Name', 'Symbol', 'Weight'],
	// The data visibly shown in your table body UI.
	body: tableMapperValues(sourceData, ['name', 'symbol', 'weight']),
	// Optional: The data returned when interactive is enabled and a row is clicked.
	meta: tableMapperValues(sourceData, ['position', 'name', 'symbol', 'weight']),
	// Optional: A list of footer labels.
	foot: ['Total', '', '<code>31.7747</code>']
};

Finally, we pass our table source data to the component for display. The interactive prop is optional, but indicates the table is interactive, and will provide meta data via the on:selected event when a row is clicked clicked.

html 
<Table source={tableSimple} interactive={true} on:selected={mySelectionHandler} />

Table Utilities

The following utility methods allow you to format your source data for use within a Table component.

typescript 
import { tableMapperValues } from '@skeletonlabs/skeleton';>

Combines Source Mapper and Source Values methods to handle both operations at once. This allows you to use the same source object, but format differently between display (body) and selected response (meta). It's recommended to use this in most use cases.

typescript 
tableMapperValues(sourceData, ['name', 'symbol', 'weight'])

//	[
//		['Hydrogen', 'H', '1.0079'],
//		['Helium', 'He', '4.0026'],
//		...
//	]
