title: ItemClicked to show data in tableview
body: <p>I choose the directory with the input files, and it is shown in the right part of tab.</p>
  <p>In my case, I want to see the contents of each input file, when I click on it, in the left part of the tab. I use <em>qt.list.itemClicked</em> to choose the file, which should be shown in <em>qt.tableView</em> However, for now, it's just exits with the exit code -1073740791 (0xC0000409)</p>

  <p>Have you got solution?</p>
  <p>My code:</p>
  <pre><code>import sys
  import os
  from PyQt5 import QtWidgets
  import design
  import pandas as pd
  
  class interface(QtWidgets.QMainWindow, design.Ui_MainWindow):
      def __init__(self):
          super().__init__()
          self.setupUi(self)
          self.new_analysis.triggered.connect(self.browse_input_folder)
          self.listOfInputs.itemClicked.connect(self.input_show)
      def browse_input_folder(self):
          directory = QtWidgets.QFileDialog.getExistingDirectory(self, 'Выберите папку с исходными данными:')
          if directory:
              for file_name in os.listdir(directory):
                  self.listOfInputs.addItem(file_name)
      def input_show(self, filename):
          input_file = pd.ExcelFile(filename)
          table = pd.read_excel(input_file, names=['Время, час', 'S3', 'S1', 'e1', 'e3'], skiprows=1, usecols='A:E')
          self.tableShow.clear()
          self.tableShow(table)
  
  def main():
      app = QtWidgets.QApplication(sys.argv)
      window = interface()
      window.show()
      app.exec_()
  if __name__ == '__main__':
      main()
