Re: Copy only the rows with data from table to another table
To Clarify...
In Filter Array:

First box: any column in your dynamic content "List rows present in a table"
Second box: "is not equal to"
Third: <leave this blank>
In Apply to Each:

input is "Body" from Filter Array.
And then in assigning values to each column in "Add Row To Table", use the expression:
items('Apply_to_each')?['put_your_colum_name_here']
