This post recorded some of excel formulas used in my work:

Delete Empty Rows 

Add the "Blanks" column to the end of the table and insert the following formula in first cell of the column: 
=COUNTBLANK(A2:C2).


This formula, as its name suggests, counts blank cells in the specified range, А2 and C2 is the first and last cell of the current row, respectively.

Copy the formula throughout the entire column. 

Now we have the key column in our table :). Apply the filter to the "Blanks" column (see the step-by-step instructions above) to show only rows with the max value (3). Number 3 means that all the cells in a certain row are empty.

Now you can remove the helper column.
