Add @activewidgets/svelte to your project dependencies -

> npm i --save @activewidgets/svelte

Now you can import ActiveWidgets component classes -

import { Datagrid } from "@activewidgets/svelte";

and use them like any standard Svelte component.

<script>

import { Datagrid } from '@activewidgets/svelte';
import './styles.css';

let rows = [
    { message: 'Hello, World!' }
];

</script>

<Datagrid {rows} />

You have to provide columns and rows properties to the datagrid to show some data. The properties of each column object define how the data will be rendered -

• field - where the cell data comes from (string|function)
• header - column header (string|object)
• width - column width (number, in pixels)
• align - cell text alignment (left|right|center)
• format - number/date format (string|function)
• fixed - fixed (true/false) for columns on the left or right side

The style (string|object) or className properties allow to change the styling of the column and cell elements.

<script>
// ...

const columns = [
  {header: 'Code', field: 'customerID', width: 80, style: 'background:#def', fixed: true},
  {header: 'Company Name', field: 'companyName', width: 160},
  {header: 'Contact', field: 'contactName', width: 120},
  {header: 'Title', field: 'contactTitle', width: 120},
  {header: 'Address', field: 'address', width: 120, align: 'right'}
];

const rows = northwind.customers;

</script>

<Datagrid {columns} {rows} />

In addition to the standard DOM keyboard and mouse events the datagrid emits composite mouse event which makes it easier to find the elements affected by the user action -

<script>
// ...

function onMouse({row}){
    alert(`row ${row.key} clicked!`);
}

</script>

<Datagrid {columns} {rows} on:mouse={e => onMouse(e.detail)} />
