HTML tables - telling whats wrong from the display

For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))

Tips on tables .... or how to spot the bug based on what's wrong on the display.

* If text that SHOULD appear in an HTML table appears above the table, then you've not put that text in a <td>...</td> tag set; it's very common for people to add un-necessary <br> tags to move on to the next row and this shoes up as a big white gap above the table!

* If the table appears at the end of your page rather than where you want it, you've probably forgotten your </table> tag. Tables gather up information to be drawn when the end-table tag is found, and if there isn't one there ... ((By the way, if you have a Netscape browser the table won't appear at all if you leave off the </table>))

* If you wanted the table right across your browser window or frame, but it's limited in width, add a width=100% into your <table> tag.

* If you want your table headers to be bold and centred, use a <th>...</th> tag pair rather than a <td>...</td>

* If the table display isn't what you expected, add a border=1 attribute to the <table> tag for testing and debug purposes - then you'll see how the table is constructed.
