HTML Table - 当table宽度为100%时保持列宽比例

Question

默认的 html <table> 元素似乎是如何设置列宽的，我 want/expect 直接开箱即用。当我尝试将整个 table 宽度设置为 100% 时会出现问题，在这种情况下，每个合理大小的列都会对齐总宽度的 1/n %。

这是我所说的例子

第二个 table 看起来很糟糕。绝对没有必要在第一列开始换行，尤其是现在有更多个可用空间时。

唯一不同的是第二个table设置为width:100%。当然，您可以在每一列上设置精确的像素或百分比尺寸以相对于彼此缩放，但这开始硬编码一些关于每一列将有多大的猜测工作。在这种情况下，只有 View 或 Edit 链接的列可以非常小，不需要占用任何额外空间，而一些可以使用更多的空间来增长，例如 Name/Type 可能有其他 longer/shorter 值。

问：我能否以某种方式保持比例列格式，同时允许整个 table 的大小为可用宽度的 100%？

像这样？

注意： 我从两个表中删除了 width:100%，没有这个 CSS 效果最好设置！

Answer 2

这是解决方案的尝试

按原样利用 table 的初始呈现来建立相对列大小。遍历每个并明确设置大小，以便在 table 以编程方式将大小调整为 100%

后它们将保持相同的比例

function LockColumnWidthAndResize($table) {
    $table.find('tr th').each(function() {
      $(this).width($(this).width())
    });
    $table.width("100%");
}

优点：不需要提前对内容的宽度进行硬编码
缺点：有点笨拙，内容有点乱。

$(function() {

  LockColumnWidthAndResize($('#example2'))

  function LockColumnWidthAndResize($table) {
    $table.find('tr th').each(function() {
      $(this).width($(this).width())
    });
    $table.width("100%");
  }
  
});

table {
    border-collapse: collapse;
    border-spacing: 0;
    table-layout: fixed;
}

table th {
    background: lightblue;
}

table th, table td {

Answer 3

问题是您添加到 table 标签的 table-layout: fixed 规则，只需将其删除即可。来自 w3schools:

fixed: Fixed table layout algorithm:

The horizontal layout only depends on the table's width and the width of the columns, not the contents of the cells

Allows a browser to lay out the table faster than the automatic table layout

The browser can begin to display the table once the first row has been received

table {
    border-collapse: collapse;
    border-spacing: 0;
    /*table-layout: fixed;*/
}

table th {
    background: lightblue;
}

table th, table td {
    border: lightgrey 1px solid;
    padding: .1em 0.2em;
}
