<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>Exception to be thrown on a failure to retrieve a column specified either by name or index number. </p>
<p>When a <a class="el" href="classCCfits_1_1Table.html">Table</a> object is created, the header is read and a column object created for each column defined. Thus id this exception is thrown the column requested does not exist in the <a class="el" href="classCCfits_1_1HDU.html" title="Base class for all HDU [Header-Data Unit] objects.">HDU</a> (note that the column can easily exist and not contain any data since the user controls whether the column will be read when the <a class="el" href="classCCfits_1_1FITS.html" title="Memory object representation of a disk FITS file.">FITS</a> object is instantiated).</p>
<p>It is expected that the index number calls will be primarily internal. The underlying implementation makes lookup by name more efficient.</p>
<p>The exception has two variants, which take either an integer or a string as parameter. These are used according to the accessor that threw them, either by name or index. </p>
