<SYSTEM_TASK:>
Given the following text description, write Python code to implement the functionality described below step by step
<END_TASK>
<USER_TASK:>
Description:
 I believe some preprocessing to remove elements or comments that don't "fit" a table would help.  
Manually, I copied and pasted spreadsheet cells with only tables and saved them as new files.  Then I will load those.
Step1:  Then I can immediately make some quick plots.  For instance, for each width in inch, I can plot drag or lift vs. velocity (m/s)
<ASSISTANT_TASK:>
Python Code:
skieval2d_periodic = pd.read_excel(SUBDIR+"ski-eval_2d_periodic_abridged.xlsx")
