Importing file from a server vs. desktop

I'm trying to create new query importing from excel table, not from excel sheet.

First, I created and named "table1" as below. (No Prob.)

Then, once I uploaded the excel file on "Power BI Server", and imported the file to a new query,

I couldn't find "table1" that I just made. (Problem!!)

So I tested by importing the file from my desktop directly, then I found "table1" and 3 more columns (No Prob.)

※ The Question is :

   1. Why the commands from the server & desktop call different items and colums?

   2. Is there any way to call "table1" importing data from the server?
