Table with table-layout: fixed; and how to make one column wider

So I have a table with this style:

table-layout: fixed;

Which makes all columns to be of the same width. I would like to have one column (the first one) to be wider and then rest of the columns to occupy the remaining width of the table with equal widths.

How to achieve that?

table {
  border-collapse: collapse;
  width: 100%;
  border: 1px solid black;
  background: #ddd;
  table-layout: fixed;
}

table th, table td {
  border: 1px solid #000;
}

table td.wideRow, table th.wideRow {
  width: 300px;
}

<table class="CalendarReservationsBodyTable">
  <thead>
    <tr>
      <th colspan="97">Rezervovane auta</th>
    </tr>
    <tr>
      <th class="corner wideRow">Auto</th>
      <th class="odd" colspan="4">0</th>
      <th class="" colspan="4">1</th>
      <th class="odd" colspan="4">2</th>
      <th class="" colspan="4">3</th>
      <th class="odd" colspan="4">4</th>
      <th class="" colspan="4">5</th>
      <th class="odd" colspan="4">6</th>
      <th class="" colspan="4">7</th>
      <th class="odd" colspan="4">8</th>
      <th class="" colspan="4">9</th>
      <th class="odd" colspan="4">10</th>
      <th class="" colspan="4">11</th>
      <th class="odd" colspan="4">12</th>
      <th class="" colspan="4">13</th>
      <th class="odd" colspan="4">14</th>
      <th class="" colspan="4">15</th>
      <th class="odd" colspan="4">16</th>
      <th class="" colspan="4">17</th>
      <th class="odd" colspan="4">18</th>
      <th class="" colspan="4">19</th>
      <th class="odd" colspan="4">20</th>
      <th class="" colspan="4">21</th>
      <th class="odd" colspan="4">22</th>
      <th class="" colspan="4">23</th>

Notice the first column, I want it to be 300px wide.

You could just give the first cell (therefore column) a width and have the rest default to auto

table {
  table-layout: fixed;
  border-collapse: collapse;
  width: 100%;
}
td {
  border: 1px solid #000;
  width: 150px;
}
td+td {
  width: auto;
}

<table>
  <tr>
    <td>150px</td>
    <td>equal</td>
    <td>equal</td>
  </tr>
</table>

---

or alternatively the "proper way" to get column widths might be to use the col element itself

table {
  table-layout: fixed;
  border-collapse: collapse;
  width: 100%;
}
td {
  border: 1px solid #000;
}
.wide {
  width: 150px;
}

<table>
  <col span="1" class="wide">
    <tr>
      <td>150px</td>
      <td>equal</td>
      <td>equal</td>
    </tr>
</table>

The important thing of table-layout: fixed is that the column widths are determined by the first row of the table.

So

if your table structure is as follow (standard table structure)

<table>
  <thead>
      <tr>
          <th> First column </th>
          <th> Second column </th>
          <th> Third column </th>        
      </tr>
  </thead>

   <tbody>
      <tr>
          <td> First column </td>
          <td> Second column </td>
          <td> Third column </td>        
      </tr>
  </tbody>

if you would like to give a width to second column then

<style> 
    table{
        table-layout:fixed;
        width: 100%;
    }

    table tr th:nth-child(2){
       width: 60%;
     }

</style>

Please look that we style the th not the td.

Are you creating a very large table (hundreds of rows and columns)? If so, table-layout: fixed; is a good idea, as the browser only needs to read the first row in order to compute and render the entire table, so it loads faster.

But if not, I would suggest dumping table-layout: fixed; and changing your css as follows:

table th, table td{
border: 1px solid #000;
width:20px;  //or something similar   
}

table td.wideRow, table th.wideRow{
width: 300px;
}

What you could do is something like this (pseudocode):

<container table>
  <tr>
    <td>
      <"300px" table>
    <td>
      <fixed layout table>

Basically, split up the table into two tables and have it contained by another table.
