Reduce space between two td's

Question

I have a table in which there are many tr and td's

Currently it looks like this in the below image.

The area in the arrow needs to be reduced a bit. I tried adding padding but it didn't worked.

Below is the html

<table width="100%" border="0" cellspacing="0" cellpadding="5" style="background-color: #EAEFF5">
            <tr>
                <td class="label">
                    Project :
                </td>
                <td class="field" style="width: 10%;">
                    <asp:DropDownList ID="ddlProject" runat="server" Width="80%" AutoPostBack="false">
                        <asp:ListItem Value="0">--Select--</asp:ListItem>
                    </asp:DropDownList>
                </td>
            </tr>
            <tr>
                <td class="label">
                    Taluka :
                </td>
                <td class="field">

CSS

.label
    {
        width: 20%;
        height: 10%;
    }
    .field
    {
        width: 30%;
        height: 10%;
    }

Fiddle of the html

Answer 1

I modified your jsfiddle https://jsfiddle.net/g0oyxfqs/2/

table tr:first-child td {
  padding-bottom: 1px; // insert total padding length here
}

table tr:nth-child(2) td {
  padding-top: 0;
}

Answer 2

increased or decreased the padding to adjust the space between two td's

.field, .label {
   padding: 2px;
}

Answer 3

I'd say you should remove the cellpadding property from the table and do that via css as well.
