完整的日历表格

平时写表格都直接table然后tr td就完事了，其中还是有很多不完善的，今天按照标准写了个日历，带样式。供日后写表格提供一个参考，搞前端规范还是挺重要的

css部分：

body {
    font-family: "myriad pro", arial, helvetica, sans-serif;
  font-size:16px;
  line-height:1.125em; /* Baseline grid of 18px */
}


/* tables may still need 'cellspacing="0"' in the markup */
table.cal {
    border-collapse: seperate;
    border-spacing: 0;
    text-align: center;
    color: #333;
}

.cal th, .cal td {
    margin: 0;
    padding: 0;

    margin-left: 0.2em;

demo结构：

    <tbody>
        <tr>

            <td class="null">31td>
            <td><a href="#">1a>td>

            <td><a href="#">18a>td>
            <td><a href="#">19a>td>
        tr>
        <tr>
            <td><a href="#">20a>td>
            <td><a href="#">21a>td>
            <td><a href="#">22a>td>
            <td><a href="#">23a>td>
            <td><a href="#">24a>td>

            <td class="null">1td>
            <td class="null">2td>
        tr>
    tbody>

写在最后：这就是精通css里面的一个列子，觉得很好，敲出来留恋一下。

常规表格玩了一下，那这个怎么玩？

table-layout:fixed;

automatic 默认。列宽度由单元格内容设定。
fixed 列宽由表格宽度和列宽度设定。

看了概念晕头转向，不知道有什么用。
还是来玩个列子吧。
html

<table class="users">
  <thead>
    <tr>
      <th class="row-1 row-ID">IDth>
      <th class="row-2 row-name">Nameth>
      <th class="row-3 row-job">Jobth>
      <th class="row-4 row-email">Email<th>
    tr>
  thead>
  <tbody>
    <tr>
      <td>0001td>
      <td>Johnny Fivetd>
      <td>Robotin'td>
      <td>[email protected]td>
    tr>
    <tr>
      <td>0002td>
      <td>Super Superlonglastnamesmithtd>
      <td>Doin' stufftd>
      <td>[email protected]td>
    tr>
  tbody>
table>

css

.users {
  table-layout: fixed;
  width: 100%;
  white-space: nowrap;
}
.users td {
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}

/* Column widths are based on these cells */
.row-ID {
  width: 10%;
}
.row-name {
  width: 40%;
}
.row-job {
  width: 30%;
}
.row-email {
  width: 20%;
}

效果就像这样：http://codepen.io/chriscoyier/full/xFcrp

这时候再回来看看概念。很明了。

fixed的时候 不管你对td设置什么样式padding什么的。他不会超过设置的20%；
而默认的情况下就会随之内容的增加而扩充的。that’s 以上。
