My only guess would be repeatedly calling the `org-table-put' function
from inside of your inner while loop. Specifically including the ALIGN
option to the function is repeatedly re-aligning your table. Maybe
performance would be improved by calling `org-table-align' once after
the end of your while loop, rather than in every loop execution.
Also, as a style point I would recommend using `map' rather than while
to iterate through the elements of the word-list.
For an additional performance gain, you may want to remove the call to
`org-table-put' altogether, and instead simply insert the word directly
and then manually adjust the location of `point' in the buffer.
Hope this helps -- Eric
