CSS applies to all tables. What if I have the “table” in a “repeater” ACF, and each table requires a different styling?

You can set different style classes in the table element.

CSS

.style1.table {
    /* your first table styles */
}
.style2.table {
     /* your second table styles */
}

HTML

<table class="style1 table">
<!--table row and cell elements -->
</table>

<table class="style2 table">
<!--table row and cell elements -->
</table>

And then you could use an “choice” field next to the table field in the repeater to let the user choose style1 or style2.

PHP

// loop through the repeater rows of data
while ( have_rows( 'repeater_field_name' ) ) : the_row();

    // get the table style choice fields value
    $tablestyle = get_sub_field( 'tablestyle' );

    $table = get_sub_field( 'your_table_field_name' );

    if ( $table ) {
        echo '<table class="' . $tablestyle . ' table">';
           // other table elements
        echo '</table>';
    }

endwhile;
