[jayzeenator]

I'm unable to create a DataTable due to this error "ValueError: is set to an invalid option 'vertical'. Must be one of: ['lr-tb', 'tb-lr', 'rl-tb', 'tb-rl', 'lr-bt', 'bt-lr', 'rl-bt', 'bt-rl']" what to do?

[HeroLove]

Does this work as a doc string
<screenname>:
Name:”screenname”
MDDataTable:
Parameters:

? It keeps giving me an error?

And is it away to pass data from a list /csv into the rows of a datatable ?

[keymediastudioitself]

For those who have an issue ValueError: is set to an invalid option 'vertical':
Solution:
1. hover a mouse cursor over MDDataTable in your file by holding CTRL and click on appeared hyperlink.
2. datatables.py will be opened in your editor. Switch to it, go: Edit - Find - Find (in PyCharm) and type in 'vertical'
3. look for:
TableRecycleGridLayout:
orientation: "vertical"
4. Change 'vertical' to 'lr-tb'
Run the app, it must work
5. Try others: ['lr-tb', 'tb-lr', 'rl-tb', 'tb-rl', 'lr-bt', 'bt-lr', 'rl-bt', 'bt-rl'] and comment how that works for you.

I try to put like this
table = MDDataTable(orientation="lr-tb",
pos_hint={'center_x': 0.5, 'center_y': 0.5},
size_hint=(0.9, 0.6),
column_data=[("Food", dp(30)), ("Calories", dp(30))],
