HtmlDoc.GetTable error?

[Start_Learning]

This is my function to display the weather in a readable format.
I abbreviate "Precipitation" with "P" and "Humidity" with "H", feel free to change it to whatever you like. :-)
Beside you can change the location to reflect your own city from this website.
This function could apply to the 5-Day forecast also.
Note: for better viewing, change the display font to mono font like "Courier New".
