/**
* The HTMLTableHeader represents an HTML table header tag.
*
* This example creates an HTMLTableHeader and displays the tag output.
*
* HTMLTableHeader header = new HTMLTableHeader();
* header.setHorizontalAlignment(HTMLTableHeader.CENTER);
* HTMLText headerText = new HTMLText("Customer Name");
* header.setElement(headerText);
* System.out.println(header.getTag());
*
* Here is the output of the tag:
*
* <th align="center">Customer Name</th>
*
* Calling getFOTag() produces the following tag with the default cell border and padding properties:
*
* <fo:table-cell border-style='solid' border-width='1px' padding='1px'>
* <fo:block font-weight='bold'><fo:block>Customer Name</fo:block>
* </fo:block>
* </fo:table-cell>
*
