The contents of Table IX-D5 is just an example. You can add 2#120 where you want, like:
<a onClick="jQuery('.wppa-dtl').css('display', 'block'); jQuery('.wppa-more').css('display', 'none'); wppaOvlResize();">
<div class="wppa-more">
Camera info
</div>
</a>
<a onClick="jQuery('.wppa-dtl').css('display', 'none'); jQuery('.wppa-more').css('display', 'block'); wppaOvlResize();">
<div class="wppa-dtl" style="display:none;" >
Hide Camera info
</div>
</a>
<div class="wppa-dtl" style="display:none;">
<br />
<table style="margin:0; border:none;" >
<tr><td class="wppa-label" >2#L005</td><td class="wppa-value" >2#005</td></tr>
<tr><td class="wppa-label" >2#L210</td><td class="wppa-value" >2#210</td></tr>
<tr><td class="wppa-label" >Date Time</td><td class="wppa-value" >E#0132</td></tr>
<tr><td class="wppa-label" >Camera</td><td class="wppa-value" >E#0110</td></tr>
<tr><td class="wppa-label" >Focal length</td><td class="wppa-value" >E#920A</td></tr>
<tr><td class="wppa-label" >F-Stop</td><td class="wppa-value" >E#829D</td></tr>
<tr><td class="wppa-label" >ISO Speed Rating</td><td class="wppa-value" >E#8827</td></tr>
<tr><td class="wppa-label" >Exposure program</td><td class="wppa-value" >E#8822</td></tr>
<tr><td class="wppa-label" >Metering mode</td><td class="wppa-value" >E#9207</td></tr>
<tr><td class="wppa-label" >Flash</td><td class="wppa-value" >E#9209</td></tr>
</table>
</div>
Note: you can also use keywords for the descriptions (e.g. 2#L120), so when you have edited them in Table X, the chnaged texts will show up.
I do not see the need to change the sequence in Table X itsself, it is just there to make the labels editable. The use of Table II-B17.x and Table II-B18.x is deprecated.
