Ich habe eine Tabelle mit einer festen Kopfzeile und einer festen ersten Spalte. Ich möchte auch die Spaltenüberschriften um 45 Grad drehen. Für den festen Titel muss eine Hintergrundfarbe festgelegt werden. Dies führt jedoch zu Problemen bei um 45 Grad gedrehten Überschriften, da der Hintergrund der nächsten Spalte den Text der vorherigen Spalte überlappt. Hier ist ein Beispiel für das Problem: .fixed_table{white-space:nowrap;margin:0;border:none;border-collapse:separate;border-spacing:0;table-layout:

尝试以下代码： .fixed_table thead th { padding: 5px; position: sticky; top: 0; z-index: 1; background-color: white; width: 25vw; /* background: transparent; */ } 我希望这会有所帮助。

Tabelle mit fester Kopfzeile und gedrehten Spaltenüberschriften-Fragen und Antworten zum chinesischen PHP-Netzwerk

Ich habe eine Tabelle mit festem Kopf und fester erster Spalte. Ich möchte auch die Spaltenüberschriften um 45 Grad drehen.

Behobener Titel muss Hintergrundfarbe festlegen. Dies führt jedoch bei um 45 Grad gedrehten Titeln zu Problemen, da der Hintergrund der nächsten Spalte den Text der vorherigen Spalte überlappt. Hier sind Beispiele für Fragen:

.fixed_table {
  white-space: nowrap;
  margin: 0;
  border: none;
  border-collapse: separate;
  border-spacing: 0;
  table-layout: fixed;
}
.fixed_table td,
.fixed_table th {
  padding: 5px;
}
.fixed_table thead th {
  padding: 5px;
  position: sticky;
  top: 0;
  z-index: 1;
  width: 25vw;
  background: #F8F9FA;
}
.fixed_table td {
  background: #F8F9FA;
  padding: 5px;
  text-align: center;
  border: 1px solid #ccc;
}

.fixed_table tbody th {
  text-align: left;
  position: relative;
}
.fixed_table thead th:first-child {
  position: sticky;
  left: 0;
  z-index: 2;
}
.fixed_table tbody th {
  position: sticky;
  left: 0;
  background: #F8F9FA;
  z-index: 1;
}

th.rotate {
  /* Something you can count on */
  height: 140px;
  white-space: nowrap;
}

th.rotate > div {
  transform: 
    /* Magic Numbers */
    translate(25px, 51px)
    /* 45 is really 360 - 45 */
    rotate(315deg);
  width: 30px;
}
th.rotate > div > span {
  border-bottom: 1px solid #ccc;
  padding: 5px 10px;
}

Hat jemand eine Lösung, um (a) die Kopfzeile festzuhalten und keine Datenzeilen anzuzeigen, die dahinter nach oben scrollen, und (b) alle um 45 Grad gedrehten Kopfzeilen weiterhin korrekt anzuzeigen?

Vielen Dank im Voraus!
