Goodies Thoughts - Table Tuning Time
Tables are always a hot topic in the HTML development arena. And
why wouldn't they be?! They are an immensely powerful tool in the design
arsenal, providing one of the easiest ways to lay out information in an easy to
read and easy to understand format. They also provide a great way to place
different items relative to each other on the page. There's a huge amount that
can be said about them, and it's certainly not the intent to give a description
of all their capabilities in this newsletter! Instead, I want to take a quick
look at some particular features that solve a lot of the problems I am
I've got a sample table here and I'd like to point out that it is a sample for illustration purposes only - the numbers in it were invented in my household and have no basis in anything to do with reality (unless by extreme coincidence or divine providence!)
First, here's the table code:
<table border="1" style="border-collapse: collapse" bordercolor="#111111" width="300">
<td width="25%" rowspan="2"> </td>
<td width="50%" colspan="2">
<p align="center">Sometimes Drink</td>
<td width="25%" rowspan="2">
<td width="25%" align="center">Coffee</td>
<td width="25%" align="center">Tea</td>
<td width="25%" align="center">Males</td>
<td width="25%" align="center">Females</td>
For your convenience, there's a copy of it in a sample page here:
If you're not familiar with html tables, you can get to know them through the tutorial series here:
In this sample table you'll notice that I have set the table's width to 300 pixels with width="300" in the <table> tag. From that point on I use percentages to specify the width of the cells, etc., so that should I choose to change to overall size of the table, the cells would continue to occupy the same proportion of the available space within the table.
The table has four rows defined (that's the four <tr> </tr> tag pairs.) Looking at rows three and four you can see that there are also four table data columns defined (the <td> </td> tag pairs.) Each of the columns is defined as 25% of the available width (which, as previously mentioned, was set in the <table> tag.)
The first two rows illustrate one of the really useful features of table formatting. This is the ability to define a cell that occupies more than one row, or more than one column by use of the rowspan and colspan attributes. You could also similarly span both multiple rows and multiple columns with a single cell.
In the first row, the first and last cells are each defined as spanning two rows. The second cell is defined as spanning the two center columns. When it comes to the third row, the outer two cell spaces have already been taken by the double row cells in the first row. Consequently, there are only two cells defined, being those that occupy the two central columns.
Personally, I find it very useful to sketch out a table on squared paper before I write its code. That way I can see where the cells will span multiple rows and/or columns, as well as where there are fewer cells specifications needed. If you put an extra cell into your table, all kinds of strange things can happen to it! It sometimes can lead to a real headache when trying to find such an error! That's when the sketch comes in really handy!
Do you know what "deprecated" means? Find out next week as we look at a newer and better definition for this table.
Thanks for Reading!

Questions are taken from submissions to our Community Mentors. You can ask a Mentor a question by going to http://www.htmlgoodies.com/mentors.
Q. I am trying to set up a clock that will count down from 72 hours : minutes : seconds over and over again. Can you tell me how I might do that?
It only counts minutes and seconds, but with a little tweaking it could be set to do what it appears you want it to do.
Q. How do I lose the blue line that appears round an image when I make it a link?
A. In the IMG SRC tag add this:
Q. Is there any way to place text on top of pictures?
A. Here is the link to see how that's done: http://www.htmlgoodies.com/tutors/textonimages.html
Q. I am constantly creating files (pdf or word) files that I need to show to many co-workers. Instead of having to email everyone everytime I finish a file, I would like to upload the file to my server and have them view the list of files online and download the ones they want. These files need to be password protected as different people in different departments should only see files pertaining to them. Here was my idea, create a bunch of password protected folders on a server - one for each department, and I will upload the file to any folder that should be allowed to view these files. Two questions: 1) I put the files in a folder, but when I try to view the folder in a browser it tells me I don't have permission to access this folder (I assume because I never created an index file). How can I set it up that I should be able to view a list of files that are in the folder? 2) how can I create a page that will allow me to upload files to folders using a browser?
A. I believe you are correct in that you do not have an INDEX file for the server to show when you try to access the folder. You could create an INDEX file with the links to the documents for downloading. I am assuming that you have already password protected the folder? An even easier way would be to use a password log in feature for your pages. The application would allow users to sign up themselves and you would control which group the user should be in and only the documents or files you allow each group or person to view. There is a nice web application called ASPLogin. It has to run on a server that supports ASP. For example, to make a document available to all users in a group called 'management', members of a group called 'administrators' and a user called 'fred' (who may or may not be in either of the groups), you would add the following code to the top of the document:
<%@ LANGUAGE=VBScript %>
Any other group or person trying to see that document will not be allowed to see it. It is a pretty slick application You can take a look here: http://www.asplogin.com
To create a page to allow you to upload documents would call for some scripting. This all depends on what type of server you site is hosted on. If it is a Windows server then it will support Active Server Pages (ASP).
Q. Is there was a way to position a background image in the center of a page regardless of screen resolution?
A. This code will position the image in the center:
background-image : url(image.jpg);
background-position : center center;
background-repeat : no-repeat;
To position in the center of a table, try using this (be sure to replace __ with the height and width of the image):
<table height="100%" width="100%">
<tr><td valign="center" align="center">
<table height="__" width="__" background="image.jpg">

Every week a site is selected for review. Each week, reviews of the previous week's selected site are chosen for publication on the HTML Goodies website.
The current week's selected site is published in Goodies To
Go and in the Peer Reviews section of the website.
Current contact email addresses for submitting your site and
for submitting reviews are published in Goodies To Go.
If you would like to have your site reviewed, sign up for the Goodies To Go newsletter in the Navigation Bar on the left side of this page.

1869 Suez Canal Opened
Not then the major shipping lane that it now is, the Suez was only 25 feet deep, 72 feet wide at the bottom, and 200 to 300 feet wide at the surface when it opened on this day in 1869. The opening ceremony was attended by French Empress Euginie, wife of Napoleon III. In its first year of operation less than 500 ships sailed its length between the Mediterranean and the Red seas. The Suez Canal has been the subject of many disputes and has been closed several times in its history. In 1875 Britain bought out the Egyptian governor's stock in the canal and as the major stockholder, undertook major improvements to the canal. Today about 50 ships daily navigate the canal, carrying 300 million tons of goods annually.
Today was also the day that: in 1558 Elizabeth I ascended the throne of England; 1800 the US Congress held its first session; 1927 a tornado hit Washington DC; 1948 Britain nationilzed their steel indstry; 1967 Beetles Ltd. and Apple Music Ltd. swapped names; 1973 President Nixon said (to AP) ".. people have got to know whether or not their President is a crook. Well, I'm not a crook."; 1980 John Lennon released "Double Fantasy" album in the UK; 1988 Benzir Bhutto elected in Pakistan; 1993 US Congress voted in favor of the North American Free Trade Area (NAFTA);
Born today were: in 1755 King Louis XVIII of France; 1790 mathematician August Ferdinand Mobius; 1925 actor Rock Hudson; 1937 comedian Peter Cook; 1938 folk singer Gordon Lightfoot; 1942 film director Martin Scorsese; 1943 model/actress Lauren Hutton; 1944 actor/director Danny De Vito; 1958 actress Mary Elizabeth Mastrantonio; 1964 Cuban video jockey Daisy Fuentes; 1964 US figure skater Marina Tcherkasova; 1980 musician Clarke Isaac Hanson;
