Perform transformations on a table in each row

I have many pdf files within a folder. My first source is Folder.Contents on the folder which results in a column that has tables containing the pdf data. 

My problem is that each table needs transposed before it is combined with the other ones. Is there a way I can send every row into a series of steps and then append it to the main table?

My queries are on my GFE so I will do my best to provide explanations, but I cannot get screenshots of my queries or steps.

Thank you in advance,

Kevin
