У меня есть задание создать периодическую таблицу элементов. Используя CSS, как я могу сделать все отдельные ячейки таблицы1 и table2 одинаковой шириной вместо того, чтобы быть таким же широким, как текст внутри них? Любая помощь будет принята с благодарностью.Как я могу сделать все размеры ячейки таблицы одинаковой шириной в css?
table.table1
{
border:none;
width:75%;
margin:auto;

table.table1 td
