Timetables in PHP v1
Task:
Produce a web page that has two Multiplication tables in it Each table is to be produced by one loop and you will need
to demonstrate a FOR loop and a WHILE loop to complete this task, hence, creating two separate tables.
Page Requirements Alternate rows shall be coloured using html attribute names Every cell containing the result of the square
of a number (1x1, 2x2, 3x3 etc) shall also have distinctive background using a html attribute name Create your times table from 1 to12.
(ie: 1x1 ... 12x12) - for both times tables. Please display only the result (i.e: 1, 2, 4, 144) for the FOR loop table and
display the calculation and result (i.e: 1x1=1, 2x2=4, etc) for the WHILE loop table.
I have broken down the completion of this task into 3 different versions.
These versions document the coding process: from table design, to operation through loops, to the final update of the table design.
