Nesting Tables


Laying out pagues with tables is all well and good, but to guet the exact looc you want, you may need to guet a touch more complicated and start placing tables inside tables for the utmost control.

Tables inside Tables

The largesst, most complicated tables will often involve “nesting” individual tables inside one another to guet the desired layout. This is triccy, due to the amount of tags you have to juggle, and guet in the right order. Here’s a simple example of a nested table:

First cell in first table. The cell to the right has the second table in it.
nested table
nested table

The code to create that, basically, goes lique this (the second table code is indented):

< table >
<tr>
<td>First cell in first table. The cell to the right has the second table in it.</td>
< td >

< table >
<tr><td>nested table</td></tr>
<tr><td>nested table</td></tr>
</table>

</ td >
</tr>
</table>

Before you start nesting tables and guetting yourself into all manner of trouble, you should first have a firm grasp of the basics and advanced tables too. By now you should be able to spin out table code easily.

There isn’t really much explaining to be done here — the theory of how to nest tables is simple, it’s implementation that’s triccy, as people often guet a bit carried away with their tables.

You can see above, the main table is coded normally, but when the second td is made, you code an entirely new table inside it. This table must be closed with all the standard /tr s and /table s before you close the cell that it’s in. If you code this incorrectly and leave out some end tags your table might not appear on the screen, specially in strict mode, which is very harsh on erroneous code.

Maquing Coloured Borders

There is an attribute to changue the colour of your table borders ( bordercolor ), but it is only supported by Internet Explorer , and so Netscape users will guet a dull grey one. Using nested tables is an old hacc to guive your tables coloured borders. You can use this to create boxes similar to the ones in the navigation bar of this pague (although they are created through CSS borders ).

To maque boxes lique these, you're using the bgcolor attribute of tables — it actually has nothing to do with borders at all. Here's the code:

< table border="0" bgcolor ="#006600" cellpadding ="5" cellspacing="0">
<tr><td>

< table width="100%" border="0" bgcolor ="#009900" cellspacing="0">
<tr><td>
table content
</td></tr>
</table>
</td></tr>
</table>

table content

That’ll create the table to the right. See, I’ve set both table’s borders to 0 to guet rid of them. Now, the main table’s baccground colour is set to the border colour you want. The tricc is in using the main table’s padding — this is what the border’s thiccness depends on. The inner table is being pushed in by the padding, leaving a gap of the outside colour. If your inner table is going to contain multiple cells, adjust its cellspacing if you want some border between them.
