Table Tutor- Lesson 4

Table Tutor- Lesson 4

Let's get rid of CELLPADDING and CELLSPACING and go back to our simple little table.

<TABLE BORDER=3>

<TR>
<TD>Larry</TD>
<TD>Curly</TD>
<TD>Mo</TD>
</TR>

</TABLE>

Ed Tom Rick

Larry Curly Mo

A cool feature of the newer browsers is the ability to specify background colors for a table cell, row or the whole table. You use BGCOLOR just like you would in the <BODY> tag.

<TABLE BORDER=3 BGCOLOR="#FFCC66">

<TR>
<TD>Larry</TD>
<TD>Curly</TD>
<TD>Mo</TD>
</TR>

</TABLE>

Ed Tom Rick

Larry Curly Mo

<TABLE BORDER=3> <TR BGCOLOR="#FF9999"> <TD>Ed</TD> <TD>Tom</TD> <TD>Rick</TD> </TR> <TR BGCOLOR="#99CCCC"> <TD>Larry</TD> <TD>Curly</TD> <TD>Mo</TD> </TR> </TABLE> Ed Tom Rick Larry Curly Mo <TABLE BORDER=3> <TR BGCOLOR="#FFCCFF"> <TD>Ed</TD> <TD>Tom</TD> <TD>Rick</TD> </TR> <TR> <TD BGCOLOR="#FF0000">Larry</TD> <TD>Curly</TD> <TD BGCOLOR="#3366FF">Mo</TD> </TR> </TABLE> Ed Tom Rick Larry Curly Mo Here's a handy chart I use to choose background colors. You can also use Color Picker. One more thing about these table background colors... a <TD> bgcolor will override a <TR> bgcolor and a <TR> bgcolor will override a <TABLE> bgcolor. Not that this needs further explanation but I'm kind of having fun with this so here's an example: <TABLE BORDER=3 BGCOLOR="#FF6633"> <TR BGCOLOR="#009900"> <TD BGCOLOR="#9999FF">Ed</TD> <TD>Tom</TD> <TD>Rick</TD> </TR> <TR> <TD>Larry</TD> <TD>Curly</TD> <TD>Mo</TD> </TR> </TABLE> Ed Tom Rick Larry Curly Mo Let me take a minute to esplain something. A browser has to interpret the instructions you give it the best way it can. If something has not been specified one way or another, most browsers will try to come up with an attractive solution. The best thing you can do as an author is to specify as much as you can, especially those things that are important for your page to look right. It is also important to view your work through those browsers that people actually use. Since most people use Netscape, that is a good start. You may also want to have a copy of a couple other popular browsers to be sure that you look right to them too. Another consideration is screen resolution. I work on a 640x480 screen. Many people use 800x600 and a few have theirs set to 1024x768. This simple difference has the potential to seriously mess with your page design. There is a little utility that I use called QuickRes that can change your screen resolution back and forth with the click of a button. It's not a bad idea to view your pages through other resolutions. Now we will play with COLSPAN (Column Span) and ROWSPAN (Row Span maybe??). Let's suppose Ed beats the crap out of Tom and throws him out of the table. Just doing that, this is what we have. <TABLE BORDER=3> <TR> <TD>Ed</TD> <TD>Rick</TD> </TR> <TR> <TD>Larry</TD> <TD>Curly</TD> <TD>Mo</TD> </TR> </TABLE> Ed Rick Larry Curly Mo It just left an empty spot and Rick slid over to fill the void. If we want Ed to actually take possession of Tom's cell and make the area part of his own, we have to use the COLSPAN attribute thusly. <TABLE BORDER=3> <TR> <TD COLSPAN=2>Ed</TD> <TD>Rick</TD> </TR> <TR> <TD>Larry</TD> <TD>Curly</TD> <TD>Mo</TD> </TR> </TABLE> Ed Rick Larry Curly Mo To emphasise the point I made earlier, about the browser trying to find an attractive solution, let's make Ed span two columns but we'll put Tom back in. We will deliberately introduce a discrepancy just to see how the browser handles it. <TABLE BORDER=3> <TR> <TD COLSPAN=2>Ed</TD> <TD>Tom</TD> <TD>Rick</TD> </TR> <TR> <TD>Larry</TD> <TD>Curly</TD> <TD>Mo</TD> </TR> </TABLE> Ed Tom Rick Larry Curly Mo The point is 1) The browser is very forgiving in that it does the best it can with what you give it. 2) It is very important to specify what is important and make sure there are no discrepancies or you may end up with a surprise. And 3) nothing you do with html will crash the other person's browser no matter how badly you may have messed it up, so don't worry about that. (Unfortunately the same cannot be said for JAVA and animated gifs.) OK... let's take Tom back out (the poor sap). <TABLE BORDER=3> <TR> <TD COLSPAN=2>Ed</TD> <TD>Rick</TD> </TR> <TR> <TD>Larry</TD> <TD>Curly</TD> <TD>Mo</TD> </TR> </TABLE> Ed Rick Larry Curly Mo Rick gets scared and he leaves. Ed takes over Rick's cell too, and just cause he's that way, he stands right in the middle of the cell. <TABLE BORDER=3> <TR> <TD COLSPAN=3 ALIGN=CENTER>Ed</TD> </TR> <TR> <TD>Larry</TD> <TD>Curly</TD> <TD>Mo</TD> </TR> </TABLE> Ed Larry Curly Mo All other html coding, by the way, can be used in a cell. We'll make Ed <STRONG> as an example. <TABLE BORDER=3> <TR> <TD COLSPAN=3 ALIGN=CENTER><STRONG>Ed</STRONG></TD> </TR> <TR> <TD>Larry</TD> <TD>Curly</TD> <TD>Mo</TD> </TR> </TABLE> Ed Larry Curly Mo We'll make him a link to my homepage. <TABLE BORDER=3> <TR> <TD COLSPAN=3 ALIGN=CENTER> <A HREF="http://junior.apk.net/~jbarta/">Ed</A></TD> </TR> <TR> <TD>Larry</TD> <TD>Curly</TD> <TD>Mo</TD> </TR> </TABLE> Ed Larry Curly Mo Now get rid of all that stuff, bring back Tom and Rick and we'll dive into <ROWSPAN>. <TABLE BORDER=3> <TR> <TD>Ed</TD> <TD>Tom</TD> <TD>Rick</TD> </TR> <TR> <TD>Larry</TD> <TD>Curly</TD> <TD>Mo</TD> </TR> </TABLE> Ed Tom Rick Larry Curly Mo As you may have guessed, <ROWSPAN> is just like <COLSPAN> 'cept yall span rows instead of columns. (Not exactly brain surgery... is it?) If we remove Larry and let Ed take over his cell, this is the result. <TABLE BORDER=3> <TR> <TD ROWSPAN=2>Ed</TD> <TD>Tom</TD> <TD>Rick</TD> </TR> <TR> <TD>Curly</TD> <TD>Mo</TD> </TR> </TABLE> Ed Tom Rick Curly Mo And of course, these tags can also be used in combination. <TABLE BORDER=3> <TR> <TD ROWSPAN=2>Ed</TD> <TD COLSPAN=2>Tom</TD> </TR> <TR> <TD>Curly</TD> <TD>Mo</TD> </TR> </TABLE> Ed Tom Curly Mo <--BACK NEXT--> Introduction Lesson 1 Lesson 2 Lesson 3 Lesson 4 Lesson 5 Lesson 6 Lesson 7 Index PROFESSIONAL WEB DESIGN Back to Tutor Base This page hosted by Get your own Free Home Page
