To make it easier to understand how tables have been set up, the border and individual cells are visible. This table can be viewed at various window sizes. It will look ok independent of whether you have your browser set to use the whole screen or only half of it. Titles like Name, Address, Phone, should be separated by a small space from the actual data. The chosen solution was to add empty columns where necessary.
Tables are a very powerful tool and there are lots of possibilities and tricks.
For example it is also possible to use tables within tables etc. It should be no problem to fill a whole booklet with information on using tables. This here is only a short introduction and not even all the options for the tags have been mentioned. Take it as a foundation on which you can build.
