Bootstrap centers the table - html

Question

I am new to twitter bootstrap 3.
The problem is the following bootstrap code always Centers the table:
I tried to find a class which may make table so on the left side of page but so far no luck.
Is there such a class and why table show on center?
<div id="registerdiv3" class="row">
<div class="col-lg-5 ">
<table>
<tr>
<td id="regPageTitle">User Registration </td>
</tr>
<tr>
<td>User Name:</td>
<td>
<asp:TextBox ID="txtUserName" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>Password:</td>
<td>
<asp:TextBox ID="txtPassword" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>Confirm Password:</td>
<td>
<asp:TextBox ID="txtConfirmPassword" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>Email:</td>
<td>
<asp:TextBox ID="txtEmail" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td></td>
<td>
<asp:Button ID="btnRegister" Text="Register" runat="server" OnClick="btnRegister_Click"></asp:Button>
</td>
</tr>
<tr>
<td>
<asp:Label ID="lblMessage" CssClass="lblMessage" Text="" runat="server"></asp:Label>
</td>
</tr>
</table>
</div>
</div>

Answer 1

Force registerdiv3 not to center the table.
#registerdiv3 table {
margin-left: 0px!important;
}
Not sure if you need important, but check also without.
Before the above solution, look at the definition of #registerdiv3 if it contains margin: 0 auto, that might be the cause.
Also it will be helpful for you to right click the on the element in your browser and click inspect element and see which class is causing it.
