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.

Example

github pages IIFE example

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 dependency 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>

Events

Events pass a CustomEvent object with the following params in the detail object

clickCol: event, col, key
clickRow: event, row
clickCell: event, row, key

`filterSelections`

Allows getting and setting the search or filter value. The filterSelections will update as the filter and search selection changes. Inside the object keys (matching row keys) will be used to get/set the filter and search values. Setting key to undefined or deleting it will remove filter or search setting.

example: (will preset column with key first_name to a)

<script>
  const selection = { first_name: "A" };
</script>
<SvelteTable
  columns="{columns}"
  rows="{data}"
  bind:filterSelections="{selection}"
/>

Column array object values

Option	Type	Description
`key`	String	Unique key identifying the column
`title`	String	Title for header
`value`	Function	table cell value. The function is passed row data
`[class]`	String	optional table cell class name
`[sortable]`	Boolean	optional Whether the table can be sorted on column
`[searchValue]`	Function	optional search value function. function is passed row data.

renderComponent

Defining a component can be done directly by passing the component as a value

[
  {
    key: "myColumn",
    //...
    renderComponent: myComponent,
  },
];

Or, if props need to be passed, an object with component and props can be passed.

[
  {
    key: "myColumn",
    //...
    renderComponent: {
      component: myComponent,
      props: {
        myProp: "someValue",
      },
    },
  },
];

Slots

Option	Description
`header`	slot for rendering the `tr` and `th` content. This will replace `title` in the header
`row`	slot for rendering the `tr` and `td` content. This will replace the rendering of `renderValue`
