Table structure in documents
</p>
<p>
As mentioned <a href="../../topic16/topic74/topic78.htm">previously</a>,
Documents are modeled by <font face="'Courier New',Monospaced,Monospace">
Elements</font> which are hierarchically linked according to the content
structure in the document. To manipulate a table structure it is
necessary to know how a document models HTML code for a table.
</p>
<p>
In HTML a table is coded like this
</p>
<p style=" text-align:left; font-family:'Courier New',Monospaced,Monospace; font-style:normal; text-decoration:none; font-size:12pt; font-weight:normal; color:#000000; margin-bottom:0pt; background-color:#ffffff; margin-top:6pt;" class="code">
<font face="'Courier New',Monospaced,Monospace" size="2"><table> </font>
</p>
<p style=" text-align:left; font-family:Arial,Sans-Serif; font-style:normal; text-decoration:none; font-size:12pt; font-weight:normal; color:#000000; margin-left:10pt; background-color:#ffffff; margin-top:0pt;" class="code">

<p>
Rendered inside a document above HTML code might show as follows
(display differs depending on style sheet settings)
</p>
<p>
</p>
<table style=" width:80%;">
<tr>
<td style=" width:50%;" valign="top">
<p class="table">
row 1, column 1
</p>
</td>
<td style=" width:50%;" valign="top">
<p class="table">
row 1, column 2
</p>
</td>
</tr>
<tr>
<td style=" width:50%;" valign="top">
<p class="table">
row 2, column 1
</p>
</td>
<td style=" width:50%;" valign="top">
<p class="table">
row 2, column 2
</p>
</td>
</tr>
</table>
<p>
</p>
<p>
The element strucutre to be generated inside a document has to be built
similar to the HTML code above. Above table viewed with the ElementTree
class in SimplyHTML would produce a view such as the following.
</p>
<p>
</p>
<p>
<img src="../../images/elemTree.jpg" width="408" height="420">
</p>
<p>
</p>
<p>
To manipulate a table or its parts, an application has to work on that
element strucutre and its attributes.
</p>
<p>
<b>Note: </b>To find out or try how a document's element structure look
like, SimplyHTML's ElementTree function is quite helpful. It shows a
window as shown with a tree having a node for each element in the
element structure of the currently shown document. All element
attributes are shown next to each tree node.
