尝试在HAML中创建一个表,我有以下内容:

%table
  %tbody
    %tr
      %th{:rowspan => 2} Name
      %th{:class => "leftBorderS", :colspan => 5} Monday
      %th{:class => "leftBorderS", :colspan => 5} Tuesday
      %th{:class => "leftBorderS", :colspan => 5} Wednesday
      %th{:class => "leftBorderS", :colspan => 5} Thursday
      %th{:class => "leftBorderS", :colspan => 5} Friday
      %th{:class => "leftBorderS", :colspan => 5} Saturday
    %tr
      - 6.times do
        %th{:class => "leftBorderS"} A
        %th{:class => "leftBorderD"} B
        %th{:class => "leftBorderD"} C
        %th{:class => "leftBorderD"} D
        %th{:class => "leftBorderD"} E

    - @data.each do |row|
      %tr
        - row.each do |column|
          %td{:class => "leftBorderD"}= column

Css课程:

table {
  border-collapse: collapse;
}
th {
  border: 1px solid #ccc;
  padding: 0.2em;
}
.weeklyReview .leftBorderS {
  border-left: 1px solid black;
  text-align: center;
}
.weeklyReview .leftBorderD {
  border-left: 1px dotted orange;
}
.weeklyReview .rowGray {
  background-color: gray;
}
.weeklyReview .rowWhite {
  background-color: white;
}

Rails控制器传递的示例数据:

@data = [["adam", 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 5, 5], ["boy", 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 5, 5], ["charles", 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 5, 5], ["david", 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 5, 5], ["echo", 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 5, 5], ["foxtro", 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 5, 5], ["gamma", 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 5, 5], ["helio", 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 5, 5], ["indigo", 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 5, 5],]

问题出现在代码的最后部分。我希望每个其他%tr的颜色都不同。目前默认为灰色,但这仍然意味着其他每个都必须是白色的,所以我只做了两个类来切换两个类)。另外,为了分隔天数,只有某些%td s具有实线左边框,否则它们将具有虚线边框。

对于HAML标记:

  1. 你如何跨过每一行?
  2. 如何仅将n实例应用于数据单元?
  3. have以及它应该是什么like

    我主要寻找语法,因为它可以应用于数据单元格,行,列或任何需要解析或单步执行的任何内容。

这似乎是一个CSS问题。

使用nth-of-type并忘记所有额外的课程:

table {
  background-color: salmon;
}

th {
  background: salmon;
}

tr:nth-of-type(2n) {
  background: salmon;
}
tr:nth-of-type(2n+1) {
  background: lightblue;
}

您也可以使用列:

td:nth-of-type(5n-3) {
  color: white
}
