wxGrid 行号不与 SQLite3 数据库同步

Question

我有一个从sqlite3数据库中填充的wx.grid。用户在文本控件中输入数据，然后单击"提交值"按钮。值写入数据库，然后该函数将数据库加载到网格中。该数据库具有索引，始于" 1"。桌子看起来像这样：

创建表Cycles( index整数， First整数， Second文字， Third整数， Fourth整数， Fifth整数， Sixth整数， Seventh整数， Eighth整数， 主键(index(

数据库加载时，列号跳跃并开始在'0'而不是'1'，而第一行值填充行'1'Leaving Row'0"空白。如果我将onloadtable((中的行数定义更改为'rownumb = row 1'，那么当单击"提交值"按钮时，行开始时为'1'，但是值填充了第二行离开行'1' 空白的。这是功能齐全的，可再现的代码：

import wx
import wx.lib.scrolledpanel as scrolled
import sqlite3 as sqlite
import wx.grid as gridlib

class MasterFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY,"",size=(900,400))
        panel = wx.Panel(self, -1)
        self.db = db
        self.c = self.db.conn.cursor()
        vbox = wx.BoxSizer(wx.VERTICAL)
        self.grid = wx.grid.Grid(panel)
        rowN = self.c.execute('SELECT Count(*) FROM Cycles')
        val = rowN.fetchone()
        rowNum = val[0] + 3
        self.grid.CreateGrid(rowNum,8)
        self.grid.Scroll(0,0)
        self.enterBtn = wx.Button(panel, -1, "Commit Values")
        self.Bind(wx.EVT_BUTTON, self.onEnter, self.enterBtn)
        vbox.Add(self.enterBtn)
        vbox.Add(self.grid)
        panel.SetSizer(vbox)
        panel.Fit()
    def onEnter(self, event):
        First = 1
        Second = 'mine'
        Third = 1
        Fourth = .5
        Fifth = 1
        Sixth = 20
        Seventh = 4
        Eighth = 10
        self.c.execute("INSERT INTO datatable VALUES (NULL,?,?,?,?,?,?,?,?);",(First,Second,Third,Fourth,Fifth,Sixth,Seventh,Eighth))
        self.db.conn.commit()
        self.onLoadTable()
    def onLoadTable(self):       
        self.grid.ClearGrid()      
        for row in range(12):
            rowNumb = row #+ 1
            self.grid.SetRowLabelValue(row, "%s" %rowNumb)
        meta = self.c.execute('SELECT * from datatable') 
        labels = []
        for i in meta.description:
            labels.append(i[0])
        labels = labels[1:]
        for i in range(len(labels)):
            self.grid.SetColLabelValue(i, labels[i])
        all = self.c.execute('SELECT * from datatable')
        for row in all:
            row_num = row[0]
            cells = row[1:]
            for i in range(len(cells)):
                if cells[i] != None and cells[i] != "null":
                    self.grid.SetCellValue(row_num, i, str(cells[i]))
        self.db.conn.commit()
class GetDatabase():
    def __init__(self):
        self.conn = sqlite.connect("data4.db") 
if __name__ == "__main__":
    db=GetDatabase()
    app = wx.App(False)
    frame = MasterFrame()
    frame.Show()
    app.MainLoop()

如果我添加... index =％d"％rownumb to select语句我得到sqlite3.porationalerror：近'index'：语法错误。

网格从(0,0(开始，因此尝试从 row_num中减去1，即。

self.grid.SetCellValue(row_num-1, i, str(cells[i]))
