Dynamic Cell Copies... or something.

Greetings Spreadsheet Gurus! I am back with another basic question for you, but confounding problem for me. Here is what I am trying to do.

I am trying to figure out the easiest way to copy the following format so that the Column number(text value within cell) is the only thing that increases as a column header.

Example: Spread sheet with three columns. First column is "Column 1 Description ALPHA" Second Column is "Column 1 Description BRAVO" and the third column is Column 1 Description Charlie"

I need to figure out a way to copy these three column titles 300 more times and only increase the value after "Column".

So next would be Column 2 Description Alpha, Column 2 description 2 BRAVO, then Column 2 description CHARLIE

How do I do this -> Column (x) Description Alpha, Column (x) Description Bravo, Column Description (x) Charlie

These need to increase sequentially across the row in column form. So Dragging Right instead of Dragging Down to begin the copy process.

Does that make sense? Thanks!
