in the document the caption property worked as title. But it not dispalyed.
@baohuachu2 The caption property is intended to provide an accessible label, and is not displayed.
However, Calcite can explore adding a new property that could display the caption property.
In the meantime, there is a workaround to display the value of the property in another element either above or below the Table, in addition to providing context to assistive technologies: https://codepen.io/geospatialem/pen/gONOLvg
