Set cellpadding and cellspacing in table using CSS

Use following css class:

.table-css {
    padding: 0 0 0 0;
    margin: 0 0 0 0;
    border: none;
    border-spacing: 0;
}

.table-css tr td {
    padding: 0 0 0 0;
    margin: 0 0 0 0;
    border: none;
}

For "cellpadding", we can simply use padding on table cells using CSS. E.g. for 0px of "cellpadding":

td { padding: 0px;}

For "cellspacing", we can apply the border-spacing using CSS. E.g. for 0px of "cellspacing":

table { 
 border-spacing: 0px;
 border-collapse: separate;
}

table {  
    border-spacing: 0px;
    border-collapse: collapse;
}
th, td {
    padding: 0;
}
