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>
