I need to create a simple table in Powerpoint or import in
Powerpoint. I will need to use this table in the future
many times as a template.

It's large as it will have 24 rows and 13 columns. Here
are my 2 obstacles.

1) I need to have the titles of each row at a 45 degree
angle and the text at a 45-degree angle.

2) I will need to import it into a powerpoint presentation
but will I need to create in word or excell. Once it's in
the powerpoint - I will need to work within the table, as
well.

The only math I will be doing within the table is the last
cells in the bottom row and the last cell in the column
will be the totals which I will just need to do an "auto
sum."

Any help will be much appreciated.

Thank you.
