title: How to skip default index (series column on the left) when writing data from dataframe in pandas into Excel through xlwings?
body: <pre><code>  item  sales
  0   A    100
  1   B    200
  2   C    300
  3   D    230
  4   E    470
  5   F    168
  </code></pre>
  <p>I have a dataset like above in pandas dataframe, and I wrote those data into an Excel file using xlwings, but I don't want to the series index column on the left (0,1,2,3,4...). How do I only import the table without a number index column?</p>
