I'm working on a project which requires a small portion from a large table of information to be displayed on a webpage (sort of like a magnifying glass). The display will be a table of fixed size (m by n cells).
Some of the cells will be merged. When the table updates, different sets of cells may be merged.
One way would be to have a script to parse out the relevant information, and have it output into a table (dynamically generating the HTML required).
The second way would be to have the script draw the table on its own in a canvas.
User events (such as arrow keys on the keyboard) will change the position of the focus (move the magnifying glass in a cardinal direction).
I hit a small snag with the first solution -
Is it possible to update the table on the page (including changing the structure of it) without having to refresh?
If you could point me to a relevant tutorial or example on the web, I'd greatly appreciate it.
