Столбец таблицы Flexbox с левой стороны разбит на полосу прокрутки

Question

Я создаю таблицу с использованием flexbox. Он имеет фиксированные заголовки и прокручиваемое тело. В Windows, когда полоса прокрутки добавляется в тело с помощью overflow-y: auto, выравнивание по левому краю разрывается между заголовком и строками. Потому что на окнах панель прокрутки занимает некоторое дополнительное пространство от тела, но заголовок все равно получает одинаковое пространство. Есть ли способ сделать сжатие ширины заголовка, когда панель прокрутки добавляется в тело?

Я хочу убедиться, что ширина заголовка и тела одинакова, когда имеется полоса прокрутки и даже когда она отсутствует.

&__item, &--header__item { 
 
     position: relative; 
 
     flex-basis: 20%; 
 
     flex-grow: 1; 
 
     overflow: hidden; 
 
     text-overflow: ellipsis; 
 
     &.sm, &.lg { 
 
     flex-grow: 0; 
 
     } 
 
     &.sm { 
 
     flex-basis: 40px; 
 
     } 
 
    }

Answer 1

overflow-y: overlay; 

ш orked для меня. Поскольку теперь полоса прокрутки будет занимать пространство из существующего табличного пространства, а не дополнительное пространство, заголовки столбцов и строки идеально согласованы.

Осторожно: вам нужно убедиться, что в вашем последнем столбце достаточно места, чтобы показать его содержимое после добавления полосы прокрутки, потому что от этого полосы прокрутки получает свое пространство.

Вот рабочая Demo

\t margin: 0; 
 
} 
 
.table{ 
 
\t display: flex; 
 
\t flex-wrap: wrap; 
 
} 
 
ul{ 
 
\t display: flex; 
 
\t width: 100%; 
 
\t list-style: none; 
 
\t padding: 0; 
 
\t margin: 0; 
 
} 
 
li{ 
 
\t flex: 5; 
 
\t /* width: 15%; */ 
 
\t padding: 10px; 
 
} 
 
.scrollable{ 
 
\t width: 100%; 
 
\t margin-top: 80px; 
 
} 
 
li.empty{ 
 
\t /* max-width: 12px; */ 
 
\t flex:1; 
 
} 
 
.header{ 
 
\t position: fixed;
