Package Exports

svelte-table

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (svelte-table) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

svelte-table

A relatively minimal svelte table example. Allows sorting and filtering based on column values.

Install

npm install -save svelte-table

Usage

The package includes exports for raw svelte, ES Module(.mjs)) and CJS (.js) exports. Your bundler will likely know which one to pick by using import SvelteTable from "svelte-table"

<script>
  import SvelteTable from "svelte-table";
  const rows = [
    /** data (example below) */
  ];
  const columns = [
    /** columns config (example below) */
  ];
</script>

<SvelteTable columns="{columns}" rows="{rows}"></SvelteTable>

An iife version is also available in the /dist/iife folder. This allows for easy run-time use, such as a direct uncompiled dependecy for a use outside of a svelte project.

<script src="iife/SvelteTable.js"></script>
<div id="my-table"></div>
<script>
  var rows = [
    /** data (example below) */
  ];
  var columns = [
    /** columns config (example below) */
  ];
  new SvelteTable({
    target: document.querySelector("#my-table"),
    props: { rows, columns }
  });
</script>
