public class Table

extends java.lang.Object

Null Cells and Phantom Rows

elementAt() can return null if there is no cell at the requested coordinate due to spans across areas where there are no cells, for example,

<table>
<tr><td rowspan=2>abc<td>def
</table>

In this case, calling elementAt(1, 1) would return null. Similarly, getRowTag() could return null if the requested index is a phantom row (a row that doesn't have any real cells). In the example above, the table has two rows due to the rowspan but row 1 is a phantom row and does not have a <tr> tag.

Implementation Note: the table parser is very strict, that is, <TABLE> can only contain <TR>. <TR> can only contain <TD>. Any deviation from this nesting is considered bad data and will be thrown away by the parser. In a future release, we hope to be more forgiving.

• 02/09/98 Dr. Jaron Collis, added support for and introduced a parseTable(Reader) convenience function.
