It has been asked by Arone at Stackoverflow:
I've tried to make the content of my table editable but without success: my table disappears.
Using this example, you can load your example csv table from the root directory of your sd card. The name of the file must be example.csv. The csv table can have any number of columns or rows. You can edit some cells and store it back to your sd card. In case no file is found, the default example table will be used.
You can use this example for your projects without need to adjust anything in the HTML document. And: it works with any desired number of rows and/or columns! Well, if you do not like the colors etc., there are lots of possibilities you can adjust with CSS in the header of the HTML document.
The tools extension offers the method PathToAssets which always returns the correct path to the assets.
These are all the blocks. The "main work" is done in the embedded HTML/jQuery file.
In case no file example.csv is found, the default example table will be used.
