Submit button alignment issue

I have a code in a div like below…

<div class="content">
				<table class="tbl">
					<tbody><tr>
						<td width="35%" class="space_height10"><label>Payment Type</label>:&nbsp;</td>
						<td width="65%" class="labeltd"><!--<select name="paymentTypeId" id="paymentType">
    <option value="-1"
    >Select</option>
    <option value="6" selected="selected">Miscellaneous Payment</option>


</select>

--> Miscellaneous Payment</td>

					</tr>
					<tr>
						<td height="10px" colspan="2"></td>
					</tr>
					<tr>
						<td width="25%" class="space_height10"><label>License Number</label>:&nbsp;<span class="req_field">*</span></td>
							
								
						<td width="65%" class="space_height10"><input type="text" id="paymentServicesAction_refNo" value="" name="refNo"></td>
						
					</tr>
					<tr>
						<td height="10px" colspan="2"></td>
					</tr>
					
					
						<tr>
						<td colspan="2" class="actionbutton"><input type="submit" value="Submit" name="method:getMiscellaneousCharges" id="paymentServicesAction__getMiscellaneousCharges">
<input type="submit" value="Back" id="paymentServicesAction_0">
</td>
						</tr>
					
				</tbody></table>
				</div>

I want to put two submit buttons right below the text-input box .

css used in the above code.

.space_height10 {
height:10px;
}

What changes I require in my code ?

try this


<div class="content">
	<table class="tbl">
		<tbody>
			<tr>
				<td width="35%" class="space_height10"><label>Payment Type</label>
					:&nbsp;</td>
				<td width="65%" class="labeltd"><!--<select name="paymentTypeId" id="paymentType">
    <option value="-1"
    >Select</option>
    <option value="6" selected="selected">Miscellaneous Payment</option>


</select>

--> Miscellaneous Payment</td>
			</tr>
			<tr>
				<td height="10px" colspan="2"></td>
			</tr>
			<tr>
				<td width="35%" class="space_height10"><label>License Number</label>
					:&nbsp;<span class="req_field">*</span></td>
				<td width="65%" class="space_height10"><input type="text" id="paymentServicesAction_refNo" value="" name="refNo"></td>
			</tr>
			<tr>
				<td height="10px" colspan="2"></td>
			</tr>
			<tr>
				<td class="space_height10">&nbsp;</td>
				<td class="space_height10" align="left"><span class="actionbutton">
					<input type="submit" value="Submit" name="method:getMiscellaneousCharges" id="paymentServicesAction__getMiscellaneousCharges">
					<input type="submit" value="Back" id="paymentServicesAction_0">
					</span></td>
			</tr>
		</tbody>
	</table>
</div>
