import pandas as pd

class GridTable(wx.grid.Grid):

    def __init__(self, parent, nrow=30, ncol=20):
        wx.grid.Grid.__init__(self, parent)
        #默认30行20列
        self.CreateGrid(nrow, ncol)
    
    #自动行数
    def AutoRowNums(self, cur_rows=0, to_rows=0):
        if cur_rows < to_rows:
            self.InsertRows(to_rows, to_rows - cur_rows, updateLabels=True)
        elif cur_rows > to_rows:
            self.DeleteRows(to_rows, cur_rows - to_rows, updateLabels=True)
        else:
            pass
    #自动列数
