 * ### Overview
 *
 * The `ui5-table-header-cell` component represents a column in the `ui5-table`.
 *
 * As it is tightly coupled to the `ui5-table`, it should only be used in the `ui5-table-header-row`
 * to ensure correct layout and design.
 *
 * ### ES6 Module Import
 *
 * `import "@ui5/webcomponents/dist/TableHeaderCell.js";`
