Is it simlair to Excel
Are you looking for a Right-To-Left language (RTL) input or are you just looking for an answer of how to align cell values (which could be done by formatting the cells)?
If the latter case is true, I won’t recommend to do so, since initial alignment is an indicator of the data type:
left aligned → text data type
right aligned → numeric data type
and this is a great helper in determining the data entered/imported are correctly recognized (esp. when entering dates)
