Reads the contents of a file or URL and creates a p5.Table object with its values. If a file is specified, it must be located in the sketch's "data" folder. The filename parameter can also be a URL to a file found online. By default, the file is assumed to be comma-separated (in CSV format). Table only looks for a header row if the 'header' option is included.
This method is asynchronous, meaning it may not finish before the next line in your sketch is executed. Calling loadTable() inside preload() guarantees to complete the operation before setup() and draw() are called. Outside of preload(), you may supply a callback function to handle the object:
All files loaded and saved use UTF-8 encoding. This method is suitable for fetching files up to size of 64MB.
