Problem with margin-top css

2

I'm trying to put a margin on my table, I did so:

.tab_dados {margin-top: 10px;}

And it works, the problem and when I put an input on it. He sticks to her. What can it be?

.form-group {
    margin-top: 20px;
    position: relative;
    display: flex;
    height: 45px;
    float: left;
}
.control-label {
    opacity: 0.4;
    pointer-events: none;
    position: absolute;
    transform: translate3d(5px, 22px, 0) scale(1);
    transform-origin: left top;
    transition: 240ms;
}
.form-group.focused .control-label, .form-group-select.focused .control-label {
    opacity: 1;
    transform: scale(0.75);
}
.form_campos {
    height: 31px;
    width: 100%;
    color: #484848;
    align-self: flex-end;
    padding: 5px;
    outline: none;
    border: 0 solid #484848;
    border-bottom-width: 1px;
    background: transparent;
    border-radius: 0;
}
.form_campos:hover, .form_campos:focus {
    border-color: #0091FF;
}
.form_disabled, .form_disabled:hover, .form_disabled:focus {
    border-color: #D7D7D7;
}

.tab_dados {
    width: 100%;
    border-collapse: collapse;
    text-align: center;
}
.tab_dados a {
    color: #484848;
    text-decoration: none;
}
.tab_dados th {
    background: #0091FF;
    color:#FFFFFF;
    font-style: italic;
} 
.tab_dados tr {
    height: 50px;
    border-bottom: 1px solid #D5D5D5;
}
.tab_dados tr:nth-child(odd) {
    background: #F7F7F7;
} 
.tab_dados tr:nth-child(even) {
    background: #FFFFFF;
}
.tab_dados tr:hover {
    background: #F1F1F1;
}
tfoot tr td{
    border:0;
    height: 40px;
}
.tfoot{
    width: 100%;
}
<div class="rows">
        <div class='form-group column column-7'>
            <label class='control-label' for='inputNormal'>FILTRO*</label>
            <input  type='text' class='form_campos' id='inputNormal' name='text_busca'>
        </div>
       
    </div>

                <th>CIDADE</th>
                <th>ESTADO</th>
            </tr>

Would that be it? If so, I'll explain it better ...

.form-group {
    margin-bottom: 20px;
    position: relative;
    display: flex;
    height: 45px;
    float: left;
}
.control-label {
    opacity: 0.4;
    pointer-events: none;

    transform: translate3d(5px, 22px, 0) scale(1);
    transform-origin: left top;
    transition: 240ms;
}
.form-group.focused .control-label, .form-group-select.focused .control-label {
    opacity: 1;
    transform: scale(0.75);
}
.form_campos {
    height: 31px;
    width: 100%;
    color: #484848;
    align-self: flex-end;
    padding: 5px;
    outline: none;
    border: 0 solid #484848;
    border-bottom-width: 1px;
    background: transparent;
    border-radius: 0;
}
.form_campos:hover, .form_campos:focus {
    border-color: #0091FF;

.form_disabled, .form_disabled:hover, .form_disabled:focus {
    border-color: #D7D7D7;
