Thanks Trevor for your answer and the precisely explained procedure to  
add the line to the _tableCreateHeaders command.

But, when I do so, I get a new issue : after quitting Rev, when I  
launch my stack again, the headers of the columns, not only are not  
centered anymore but also some of them are even so shifted to the  
left, that  one can't see the first characters of them; bizarre ;-)

More precisely : could be useful to say that the data grid is on a  
substack;
Even without quitting Rev :
- if I close the substack and re-open it the headers keeps centered
- If I close the substack AND its main stack, then, when I re-open  
them, I get the headers shifted to the left.

Not a big problem anyway (I can set the alignment each time a card  
opens as you suggest); but I am curious about what is happening ;-))

It was the first time I had a look at your scripts in the  
revdatagridlibrary; very impressive; "chapeau bas" ;-))
