javascript - 表列大小调整为 100% 容器高度

Question

对于 html 表格，我试图实现 100% 的容器高度以及表格列大小调整功能。即，当内容高度超过包含 div 的高度(不是 thead 和 tfoot)时，只有 tbody 应该滚动。并且应该可以调整表列的大小。出于某种原因，我只想使用一个表元素(我不想通过为 thead 和 tbody 使用单独的表来实现这一点)。

我根据给出的建议尝试了以下 fiddle here

这些是我试过的 fiddle

1. http://jsfiddle.net/Ld4uv0a4/2/

table.scroll {
    /* width: 100%; */ /* Optional */
    /* border-collapse: collapse; */
    border-spacing: 0;
    border: 2px solid black;
}

table.scroll tbody,
table.scroll thead { display: block; }

thead tr th { 
    height: 30px;
    line-height: 30px;
    /* text-align: left; */
}

table.scroll tbody {
    height: 100px;
    overflow-y: auto;
    overflow-x: hidden;
}

tbody { border-top: 2px solid black; }

tbody td, thead th {
    /* width: 20%; */ /* Optional */
    border-right: 1px solid black;
    /* white-space: nowrap; */
}

tbody td:last-child, thead th:last-child {
    border-right: none;
}

2。 https://jsfiddle.net/wwjgozqp/

.table-container {
    height: 10em;
}
table {
    display: flex;
    flex-flow: column;
    height: 100%;
    width: 100%;
}
table thead {
    /* head takes the height it requires, 
    and it's not scaled when table is resized */
    flex: 0 0 auto;
    width: calc(100% - 0.9em);
}
table tbody {
    /* body takes all the remaining available space */
    flex: 1 1 auto;
    display: block;
    overflow-y: scroll;
}
table tbody tr {
    width: 100%;
}
table thead,
table tbody tr {
    display: table;
    table-layout: fixed;
}
/* decorations */
.table-container {
    border: 1px solid black;
    padding: 0.3em;
}
table {
    border: 1px solid lightgrey;
}
table td, table th {
    padding: 0.3em;
    border: 1px solid lightgrey;
}
table th {
    border: 1px solid grey;
}

但似乎没有任何效果。谁能帮我实现这两种效果(调整列大小和 100% 容器高度)。

调整列标题大小时，您还需要更新相应的列。

这是您可以执行的操作。它可能需要一些微调，但您可以以此为起点。

//following code is used for column resize
$(function() {
  $("table").find("th").each(function(i, item) {
    var $th = $(this);
    var text = $th.text();
    $th.html("");
    var $colHandle = $("<div class='colHandle'></div>");
    var colResizer = $("<div class='colResizer'></div>").html(text).append($colHandle);
    $th.append(colResizer);
    $colHandle.mousedown(function(e) {
      var startX = e.clientX;
      $(document).bind("mousemove", function(e) {
        var width = $th.width() + (e.clientX - startX);
        $th.width(width);
        var idx = $th.index() + 1;
        $("table tr td:nth-of-type(" + idx + ")").width(width);
        startX = e.clientX;
      });
      $(document).mouseup(function() {
        $(document).unbind("mousemove");
      });
    });

  });

});

  display: flex;
