Use transparent borders if possible.

HTML
<div class="table">
<div class="row">
<div class="cell">Cell 1</div>
<div class="cell">Cell 2</div>
<div class="cell">Cell 3</div>

</div>
CSS
.table {
display: table;
border: 1px solid black;
}
.row { display:table-row; }
.cell {
display: table-cell;
background-clip: padding-box;
background-color: gold;
border-right: 10px solid transparent;
}
.cell:last-child {
border-right: 0 none;
}
You could use the border-spacing
property, as the accepted answer suggests, but this not only generates space between the table cells but also between the table cells and the table container. This may be unwanted.
If you don't need visible borders on your table cells you should therefore use transparent
borders to generate cell margins. Transparent borders require setting background-clip: padding-box;
because otherwise the background color of the table cells is displayed on the border.
Transparent borders and background-clip are supported in IE9 upwards (and all other modern browsers). If you need IE8 compatibility or don't need actual transparent space you can simply set a white border color and leave the background-clip
out.
