title: Huxtable: quick_xlsx does not display data after export
body: <p>I was successfully using <code>quick_xlsx</code> from <code>Huxtable</code> so far.
  With the code below, when I opened the exported Excel file, it shows no data and the file started with column G, excluding the mtcars columns.</p>
  <pre><code>library(huxtable)
  library(dplyr) 
  
  data(mtcars)
  car_ht &lt;- as_hux(mtcars)
  car_ht %&lt;&gt;% 
    set_all_padding(4) %&gt;% 
    set_outer_padding(0) %&gt;% 
    set_number_format(2) %&gt;% 
    set_bold(1, everywhere) %&gt;% 
    set_bottom_border(1, everywhere) %&gt;% 
    set_width(0.4) %&gt;% 
    set_caption(&quot;Mtcars&quot;) %&gt;% 
    set_text_color(2:3, 1, &quot;purple&quot;)
  
  quick_xlsx(car_ht)
