title: Get number of rows and number of columns in Excel sheet
body: <p>I am trying to read a big excel file in golang.
  I need to find the number of columns.</p>
  
  <p>I am using the <a href="https://godoc.org/github.com/360EntSecGroup-Skylar/excelize" rel="nofollow noreferrer">https://godoc.org/github.com/360EntSecGroup-Skylar/excelize</a>
  library but I could not find such a function.</p>
  
  <p>In python there is the <a href="https://xlrd.readthedocs.io/en/latest/api.html#xlrd.sheet.Sheet.ncols" rel="nofollow noreferrer">https://xlrd.readthedocs.io/en/latest/api.html#xlrd.sheet.Sheet.ncols</a></p>
  
  <p>Anything similar in Golang?</p>
