The Header Cell tag outputs a single header cell in a results table. The tag must be nested within a Header tag.

​
Usage

Place the Header Cell tag inside the body of a Header tag. The order of the cell tags within a header should match the order of the Cell tags within the table’s Row tag. In this example, a table contains three columns and displays the “full_name”, “address”, and “dob” fields for each document in the given search response. 
<table:result-list response="response">
    <table:header>
        <table:header-cell name="full_name" label="Name" sort="true"></table:header-cell>
        <table:header-cell name="address" label="Address" sort="true"></table:header-cell>
        <table:header-cell name="dob" label="Date of birth" sort="true"></table:header-cell>
    </table:header>
    ...
</table:result-list>
