Można to osiągnąć za pomocą kilku prostych linii CSS. Eliminuje to potrzebę wykonywania skomplikowanych obliczeń na podstawie wysokości i pozycji w jQuery, a ponadto ma dodatkową zaletę, jeśli chodzi o czas reakcji.
Celem jest absolutne położenie elementu tfoot
na dole elementu .sticky-table
.
Aby to zrobić, możemy podać .sticky-table
a position: relative;
i tfoot
a .
.sticky-table {
/* ...existing styles */
position: relative;
}
.sticky-table tfoot {
position: absolute;
bottom: 0;
}
Jak to:
/* Styles go here */
.sticky-table {
position: relative;
max-width: 100%;
max-height: 500px;
height: 500px;
overflow: auto;
border-top: 1px solid #ddd;
border-bottom: 1px solid #ddd;
padding: 0 !important;
}
.sticky-table table {
margin-bottom: 0;
width: 100%;
max-width: 100%;
border-spacing: 0;
}
.sticky-table table tr.sticky-row th,
.sticky-table table tr.sticky-row td {
background-color: #fff;
border-top: 0;
position: relative;
outline: 1px solid #ddd;
z-index: 5;
}
.sticky-table table td.sticky-cell,
.sticky-table table th.sticky-cell {
background-color: #fff;
outline: 1px solid #ddd;
position: relative;
z-index: 10;
}
.sticky-table table tr.sticky-row td.sticky-cell,
.sticky-table table tr.sticky-row th.sticky-cell {
z-index: 15;
}
.sticky-table tfoot {
position: absolute;
bottom: 0;
}
.sticky-table::-webkit-scrollbar {
width: 0.7em;
height: 0.7em;
}
.sticky-table::-webkit-scrollbar-track {
-webkit-box-shadow: inset 0 0 6px rgba(0, 0, 0, 0.3);
}
.sticky-table::-webkit-scrollbar-thumb {
background-color: #b37e7e;
outline: 1px solid slategrey;
border-radius: 5px;

Oblicz w jakim celu? Czy masz na myśli obliczyć odległość potrzebną do przejścia na dno w zależności od liczby rzędów? – zer00ne
Zamiast określać odległość od góry, wypróbowałeś odległość od dołu za pomocą '.css ('bottom', 0);'? – Adriano
Nie trzeba używać jQuery, aby rozwiązać ten problem. Wystarczy kilka prostych linii CSS. Dostarczyłem rozwiązanie pokazujące tę metodę. –
