The only way I found to set up language settings is here: https://docs.handsontable.com/pro/1.13.0/Options.html#language
Is there a way to do this just once, for the entire table?
You can set language and format in the main instance setting.
demo: http://jsfiddle.net/handsoncode/gfrLj8jn/
And if you wish any column to be different, like I want a Year column to stay a year a not a currency, just add the settings inside the column (line: 30).
The language and format settings won’t have any effect on cells other than numeric.
Thank you, Aleksandra! I think this should be clearer in the documentation.
Thank you for sharing the tip. We will be changing this part of documentation soon.
