title: how do I increase the width of pandastable
body: <p>I have the following in Python:</p>
  
  <pre><code>from tkinter import Tk, Frame
  from pandastable import Table
  import pandas as pd
  
  xx = Tk()
  xx.state('zoomed')
  xx.title('The Sheet')
  f = Frame(xx, width=800, height=400, bd=2)
  f.place(x=20, y=20)
  
  df = pd.DataFrame([], columns=['a', 'b', 'c', 'd', 'e', 'f'])
  df = df.append({'a': 123, 'b': 'asdf ery', 'c': 345.1, 'd': 'qweqwe qweqwe', 'e': 123.2, 'f': 45646.4}, ignore_index=True)
  df = df.append({'a': 234, 'b': 'qwersdfg sdfg', 'c': 7234.9, 'd': 'asd asd asdasd asd', 'e': 21.7, 'f': 1123.8}, ignore_index=True)
  df = df.append({'a': 456, 'b': 'zxcv xcvb', 'c': 1209.3, 'd': 'zxc zxc zxc zxc zxc zxc', 'e': 1.298, 'f': 10023.6}, ignore_index=True)
  pt = Table(f, dataframe=df, showtoolbar=False, showstatusbar=False)
  pt.show()
  
  xx.mainloop()
  </code></pre>
  
  <p>However, no matter how much I increased the <strong>Frame</strong> <code>width</code>, the displayed table remains the same size. I want to show all the six columns. How is this done?</p>
