A sample of a table
with an image in the background.
Some samples of what
can be done with bordercolor.
A
test page with several tables using no BG color, some with a BG color
or an image and playing with cellpadding and cellspacing.
A TEXT
file with the tags for a table (4 rows, 4 columns and 16 cells) along
with many of the table tags for you to experiment with.
Please go and read
this very good table
tutorial as well as this page.
META
Tags are
at th ebottom of the page.

Using TABLES in
your page layout has several key advantages:
- an excellent format
for displaying certain types of data.
- they provide more
control in the placement of text and images.
- the page layout
will display more consistently and uniformly on different browsers.
TABLES are all about
control.
You can place text,
images and links within each cell.
|
|
Table
attributes
You can
change the size and color of your table, specify a border size, and add
space between the table cells. You determine all of these things by using
several different attributes in your TABLE tag
| width |
Available
to all of the table tags. Determine the tag's width, either in px
or % |
| height |
Available
to all of the table tags. Determine the tag's height, either in px
or % |
| border |
Available
to the <table> tag. Defines its border size |
| bgcolor |
Available
to all of the table tags. Defines the background color. |
| cellpadding |
Available
to the <table> tag. Defines the padding width between each of
it's cells. |
| cellspacing |
Available
to the <table> tag. Defines the spacing width between each of
it's cells. |
| background |
Available
to all of the table tags. Specifies the background image of the table. |
|
rowspan
|
Available
to the <TD> tag only. It merges cells together from different
columns (up and down). It spans rows instead of columns. |
| colspan |
Available
to the <TD> tag only. It merges cells together in a row, across
columns (side to side). |

Boxes
Inside Of Boxes
It's probably easiest
to think of a TABLE as a flat, two dimensional box you can put on your
page.
Inside of this box
you can place other boxes, or CELLS, and inside of these boxes, you put
text, images, or even more boxes still.
|
All
tables involve using the below three tags:
|
| <table></table> |
Defines
a table. All tables begin and end with this tag. |
| <tr></tr> |
Defines
a row. A table must have at least one row (think about it). |
| <td></td> |
Defines
a cell within a row. All tables must also have a least one row. |
| CELL
1 |
CELL
2 |
| CELL
3 |
CELL
4 |
|
<TABLE
border="1" >
<TR>
<TD>CELL 1</TD>
<TD>CELL
2</TD>
</TR>
<TR>
<TD>CELL 3</TD>
<TD>CELL
4</TD>
</TR>
</TABLE> |
This
is a very simple table which contains four cells (2 rows and 2 columns).
The opening
tag for a table is <TABLE> and the closing tag is </TABLE>
The
TABLE CELL, or <TD> is the basic unit of a cell. You can
have as many or as few cells in your table as you wish.
A horizontal row of
cells is called a TABLE
ROW or <TR>.
Always remember that
cells go into rows, and rows go into a table.
This is the
most simple table with one row and one cell.
Go here for a kewl trick for images.
|
<TABLE
border="1" >
<TR>
<TD>Your
Data</TD>
</TR>
</TABLE> |
Notice how the opening and closing TD tags are nested inside of the TR
tags, and likewise, the TR tags are nested inside the TABLE tags.
| CELL
1 |
CELL
2 |
| CELL
3 |
CELL
4 |
|
<TABLE
border="1" >
<TR>
<TD>CELL 1</TD>
<TD>CELL
2</TD>
</TR>
<TR>
<TD>CELL 3</TD>
<TD>CELL
4</TD>
</TR>
</TABLE> |
In the example above,
Cell 1 and cell 2 form a table row, and cells 3 and 4 form another table
row.
In this example, I've
outlined a table with two Table Rows. Each row contains two Cells, which
gives us a four cell table.

The
Width and Height
<TABLE
WIDTH=33%> or <TABLE WIDTH=250>
Use the WIDTH attribute
inside the table tag to specify how much of the screen you want your table
to span.
You can use a percentage,
like I just did, or you can use pixels for the value.
You can also use the
WIDTH attribute within the <TR> and <TD> opening tags.
<TABLE
HEIGHT=33%> or <TABLE HEIGHT=250>
Use the HEIGHT attribute
inside the table tag to specify how much of the screen you want your table
to span.
You can use a percentage,
like I just did, or you can use pixels for the value.
You can also use the
HEIGHT attribute within the <TR> and <TD> opening tags.
|
|
Borders
You can control the
thickness of your table border by using the BORDER attribute. <TABLE
BORDER=5>
You can even lose the border altogether by indicating a value of 0 for
the BORDER attribute.
If you use HTML tables
to control the layout of your Web pages, here's one of our best browser
compatibility tips: always include the attribute BORDER="0".
Do this even though the default for the BORDER attribute is zero.
The reason for this
is that Netscape Navigator puts additional white space around each table
cell unless you explicitly set BORDER="0". If you're using your
TABLE to control the positioning of other elements within the page, this
little bit of extra space can affect alignment.
|
|
<TABLE
Border=0>
<TR>
<TD>image</TD>
<TD>image</TD>
</TR>
</TABLE> |
|

Combining
several attributes to create an interesting effect.
|
Here is a kewl
trick you can do by nesting a table inside a table and then placing
an image at the center. You create a multi colored frame.
|
|
|
<TABLE
BGCOLOR="#990B00" BORDER="5" CELLPADDING="5"
CELLSPACING="5">
<TR ALIGN="CENTER">
<TD>
<TABLE BGCOLOR="#000000" BORDER="0" CELLPADDING="10"
CELLSPACING="10">
<TR ALIGN="CENTER">
<TD>
<IMG SRC="starry.jpg" WIDTH="150" HEIGHT="138"
BORDER="0">
</TD>
</TR>
</TABLE>
</TD>
</TR>
</TABLE>
|
|
|
Coloring
Table
<TABLE
BGCOLOR="#000000"> or <TABLE BGCOLOR=black>
BGCOLOR in a table
works just like the BGCOLOR attribute in a body tag.
Use the color's name
or it's Hexadecimal code.
The BGCOLOR can be
used in the opening <TABLE>, <TD> or <TR> tags to change
the color (using hexcodes or color names).
|
Placing
it in the <TABLE> tag colors the whole table the same color.
|
| CELL
1 |
CELL
2 |
| CELL 3 |
CELL 4 |
|
<TABLE
border="1" bgcolor="#9999FF">
<TR>
<TD>CELL 1</TD>
<TD>CELL
2</TD>
</TR>
<TR>
<TD>CELL 3</TD>
<TD>CELL
4</TD>
</TR>
</TABLE> |
|
Using
it in the <TR> tag colors the whole row one color.
|
| CELL
1 |
CELL
2 |
| CELL 3 |
CELL 4 |
| CELL 5
|
CELL

|
|
<TABLE border="1">

<TD>CELL

</TR>
<TR>
<TD>CELL 3</TD>
<TD>CELL
4</TD>
</TR>
<TR
bgcolor=green>
<TD>CELL 5</TD>
<TD>CELL
6</TD>
</TR>
</TABLE>
|
|
Placing
it in the <TD> tag colors only that cell.
|
| CELL

<TR>
<TD>CELL 3</TD>
<TD
bgcolor=green>CELL 4</TD>
</TR>
<TR>
<TD bgcolor="#CCFFFF">CELL
5</TD>
<TD>CELL
6</TD>
</TR>
</TABLE>
|
|
|
SPACING
CELLPADDING
and CELLSPACING will let a little air into your table and make it easier
to view.
| CELLSPACING
is the amount of space you want between your table cells.In the example
above, I specified that I want five pixels of space between my cells.
The cell are empty in this example. |
|
<table border=1
cellpadding=0 CELLSPACING=0>
|
<table border=1
cellpadding=0 CELLSPACING=5>
|
|
<table border=1
cellpadding=0 CELLSPACING=10>
|
<table border=1
cellpadding=0 CELLSPACING=20>
|
| CELLPADDING
is how many pixels of space you want on the inside of your cell between
your text and the border. The image of the blue-black button take
up the entire space of the cell. The yellow space around the button
is the CELLPADDING. |
|
|
<TABLE
border=1 CELLPADDING=0 cellspacing=0 bgcolor =yellow>
<TR>
<TD>image</TD>
<TD>image</TD>
</TR>
<TR>
<TD>image</TD>
<TD>image</TD>
</TR>
</TABLE>
|
|
<table border=1
CELLPADDING=5 cellspacing=0>
|
|
<table border=1
CELLPADDING=10 cellspacing=0>
|
<table border=1
CELLPADDING=20 cellspacing=0>
|
|
|
Merging
Cells within Columns and Rows
Now
we will play with COLSPAN (Column Span) and ROWSPAN (Row Span).
Both
are placed in the opening <TD> tag (which defines a cell within
a row)
|
|
COLSPAN
--spans across columns
<TD COLSPAN=2>
|
|
|
COLSPAN
--spans across columns
<TD COLROWSPAN=3> |
|
|
ROWSPAN
-spans rows instead of columns
<TD ROWSPAN=2>
|
|
|
ROWSPAN
-spans rows instead of columns
<TD ROWSPAN=3>
|
|
|
You can't use colspan and rowspan in the same table cell tag. They
must be in seperate <TD> tags.
<TD ROWSPAN=2>
<TD COLSPAN=2>
|
|
|
If you do place them in the same <TD> tag then they will
merge together and instead of an "L" shaped box, it will
create a square or rectangle.
<TD ROWSPAN=2
COLSPAN=2>
|
|
Row
and Column spaning is useful for titles, layout, placing images and text,
among other things. Be creative.
|
|
Alignment
Attributes
You can position your
text or image inside of the table cell itself by using the ALIGN and VALIGN
attributes inside the <TD> tag.
It seems that the
default for the alignment inside a cell is <TD
ALIGN=left VALIGN=middle>
|
ALIGN
|
VALIGN
|
| <TD align=left> |
<TD valign=top> |
| <TD align=center> |
<TD valign=middle> |
| <TD align=right> |
<TD valign=bottom> |
Use
only one ALIGN and one VALIGN attribute per table cell or they will not
work.
<TD
ALIGN=left VALIGN=top>
| ALIGNMENT |
VALIGN=MIDDLE |
VALIGN=TOP |
VALIGN=BOTTOM |
ALIGN=LEFT
---
---

|
 |
 |
 |
ALIGN=CENTER
---

|
 |
 |
 |
ALIGN=RIGHT
---

|
 |
 |
 |
|
You
can also place tables within tables. It's similar in nesting a list
within a list.
|
|
The pale blue
table is inside cell #3 and the violet table is inside cell #8.
You can nest
as many tables within table as you like.
Notice that
the nested table is between the opening <TD> cell tag and
the closing cell </TD> tags of the table it's nested inside.

Tables are very sensitive
to having their tags broken and moved around. Extra attension must be
given to them so that they work properly. Always look at the table in
a browser to see if it's reacting properly and that all the information
is readable.
I would suggest
making a drawing of the table you wish to make. Organize the information
inside each cell the way you want it to appear. It would be easier to
code all the tags if you have a visual map, it's less confusing.

Meta
Tags
<meta name="keywords"
content="keywords here">
<meta name="description"
content="description here">
<META name="description" content="We specialize in catering

Where "keywords here" is a list of keywords that you wish to
be associated with your page, and "description here" the short
description describing it.
The meta tag is inserted
inside the <head> section. Keywords entered into the <meta>
tag should each be separated by a comma.
