<zg-head>

Interactive Storybook Playground

The <zg-head> tag is a web component that is a container for the head cells (<zg-head-cell>) of the data grid specified via the head-cell attribute found on <zg-column> tags.

The tag roughly corresponds to the idea of the <thead> tag used in HTML tables. The <zg-head> tag is generated by the library and should not be placed in a grid manually by a user. Instead, it is used as a styling target for CSS.
