Hi @Anonymous ,
Could you please share a bit more about your scenario?
Do you want to right align a column in a Data Table control?
If you want to right align a column in a Data Table control, I afraid that there is no way to achieve your needs in PowerApps currently.
Currently, there is no Align property supported within Data Table control to change the align attribute of a column. If you would like this feature to be added in PowerApps, please submit an idea to PowerApps Ideas Forum:

As an alternative solution, you could consider configure a Gallery as a Tabular GRID. Bind your Gallery to a Table data source, then within the Gallery, add several Text Input boxes as below:

Set the Default property of the Text Input box to following formula:
ThisItem.ColumnName // use this formula to reference column value from your Table data source
After that, you could set the Align property of the Text Input box to following:
Align.Right
to display the value in right align within the Text Input box.
Best regards,
