json-table

A table view from the JSON structure.

The element renders a table and / or list view from a JSON object. If JSON is an array it renders a table view. For objects it renders a list view.

Complex object are represented as an embedded view of a list or table inside the parent object representation. That may create very complex structure and lead to performance issues when computing data model and building the DOM. Therefore the element will only build the first level of the view. If the object / array contains other objects / arrays it will show only a button to display embedded objects. That should prohibit from freezing the UI while rendering the view.

Another optimization is pagination (disabled by default). After setting the paginate property array tables will contain a pagination with itemsPerPage items rendered at a time. The user can change number of items at any time.

<json-table json="[...]" paginate itemsPerPage="15"></json-table>

Content actions

The element can render an actions pane above the table / list view. Action pane is to display content actions that is relevant in context of the content displayed below the buttons. It should be icon buttons list or just buttons added to this view.

Buttons must have slot="content-action" attribute set to be included to this view.

<json-table json='{"json": "test"}'>
 <paper-icon-button slot="content-action" title="Copy content to clipboard" icon="arc:content-copy"></paper-icon-button>
</json-table>
