Twitter引导程序：Dropdownlist和Textbox无法正确对齐(Twitter bootstrap: Dropdownlist and Textbox doesn't align properly)

 我有一个带有下拉列表的表格，还有两个文本框供我的用户选择他们的生日。 它们全部都在一个表格单元格中，它们具有相同的高度值。 然而，对于我的生活，我无法弄清楚为什么他们的下拉似乎像文本框旁边的2px浮动。 下面是我的代码和图片。  
 <tr>
            <td class="tdLeft" style="padding: 10px; text-align: right">Birthdate:</td>
            <td class="tdRight" style="text-align: left">
                <asp:DropDownList ID="ddlMonth" CssClass="form-control input-lg" placeholder="Month" runat="server" Width="136px" style="display: inline; text-align: center" Height="45px">
                    <asp:ListItem Value="01">January</asp:ListItem>
                    <asp:ListItem Value="02">February</asp:ListItem>
                    <asp:ListItem Value="03">March</asp:ListItem>
                    <asp:ListItem Value="04">April</asp:ListItem>
                    <asp:ListItem Value="05">May</asp:ListItem>
                    <asp:ListItem Value="06">June</asp:ListItem>
                    <asp:ListItem Value="07">July</asp:ListItem>
                    <asp:ListItem Value="08">August</asp:ListItem>
                    <asp:ListItem Value="09">September</asp:ListItem>
                    <asp:ListItem Value="10">October</asp:ListItem>
                    <asp:ListItem Value="11">November</asp:ListItem>
                    <asp:ListItem Value="12">December</asp:ListItem>
                </asp:DropDownList>
                <asp:TextBox ID="tbMem1Day"
                    CssClass="form-control input-lg" placeholder="Day"
                    runat="server" Width="74px" style="display: inline"></asp:TextBox>
                <asp:TextBox ID="tbMem1Year"
                    CssClass="form-control input-lg" placeholder="Year"
                    runat="server" Width="124px" style="display: inline"></asp:TextBox>
            </td>
        </tr>
 

I have a table with a dropdownlist, and two text boxes for my users to select their birthdays. All three of them are in a table cell, and they have the same height value. However, for the life of me I can't figure out why they dropdown seems to be floating like 2px next to the text boxes. Below is my code and a picture. 
 <tr>
            <td class="tdLeft" style="padding: 10px; text-align: right">Birthdate:</td>
            <td class="tdRight" style="text-align: left">
                <asp:DropDownList ID="ddlMonth" CssClass="form-control input-lg" placeholder="Month" runat="server" Width="136px" style="display: inline; text-align: center" Height="45px">
                    <asp:ListItem Value="01">January</asp:ListItem>
                    <asp:ListItem Value="02">February</asp:ListItem>
                    <asp:ListItem Value="03">March</asp:ListItem>
                    <asp:ListItem Value="04">April</asp:ListItem>
                    <asp:ListItem Value="05">May</asp:ListItem>
                    <asp:ListItem Value="06">June</asp:ListItem>
                    <asp:ListItem Value="07">July</asp:ListItem>
                    <asp:ListItem Value="08">August</asp:ListItem>
                    <asp:ListItem Value="09">September</asp:ListItem>
                    <asp:ListItem Value="10">October</asp:ListItem>
                    <asp:ListItem Value="11">November</asp:ListItem>
                    <asp:ListItem Value="12">December</asp:ListItem>
                </asp:DropDownList>
                <asp:TextBox ID="tbMem1Day"
                    CssClass="form-control input-lg" placeholder="Day"
                    runat="server" Width="74px" style="display: inline"></asp:TextBox>
                <asp:TextBox ID="tbMem1Year"
                    CssClass="form-control input-lg" placeholder="Year"
                    runat="server" Width="124px" style="display: inline"></asp:TextBox>
            </td>
        </tr>

 这段代码应该有效  
tree = [('T',
  [('A1', ['B1', ('B2', ['D1'])]),
   ('A2', ['C1', 'C2', ('C3', [('E1', ['F1']), ('E2', ['G1', 'G2'])])])])]


def print_node(header, tree):
    if isinstance(tree,str):
        return [header+' '+str(tree)]
    else:
        head, tail = tree
        return reduce(lambda a,b:a+b,[print_node(header + ' ' + head,t_element) for t_element in tail])

def print_tree(tree):
    children = tree[0]
    print '\n'.join(print_node('',children))

print_tree(tree)
 
 它将结果列表保存在内存中并执行简单的递归。 print_tree只是一个以正确形式输入输入的包装器。 希望能帮助到你 ！ 

This code shall work 
tree = [('T',
  [('A1', ['B1', ('B2', ['D1'])]),
   ('A2', ['C1', 'C2', ('C3', [('E1', ['F1']), ('E2', ['G1', 'G2'])])])])]


def print_node(header, tree):
    if isinstance(tree,str):
        return [header+' '+str(tree)]
    else:
        head, tail = tree
        return reduce(lambda a,b:a+b,[print_node(header + ' ' + head,t_element) for t_element in tail])

def print_tree(tree):
    children = tree[0]
    print '\n'.join(print_node('',children))

print_tree(tree)
 
It keeps the list of result in memory and performs a simple recursion. print_tree is only a wrapper to put the input in the right form. Hope it helps !
