HTML 表格需要列间距，而不是行间距

Question

I have an HTML table. I need to have spacing between the table columns, but not the table rows.

If I use the cellspacing CSS property it does it between both rows and columns. I also cannot use CSS in what I doing. I need to use pure HTML.

Answer 1

The better approach uses Shredder's css rule: padding: 0 15px 0 15px only instead of inline css, define a css rule that applies to all tds. Do This by using a style tag in your page:

<style type="text/css">
  td {
    padding: 0 15px;
  }
</style>

or give the table a class like "paddingBetweenCols" and in the site css use

.paddingBetweenCols td {
  padding: 0 15px;
}

The site css approach defines a central rule that can be reused by all pages.

If your doing to use the site css approach, it would be best to define a class like above and apply the padding to the class...unless you want all td's on the entire site to have the same rule applied.

If you can use inline styling, you can set the left and right padding on each td .. Or you use an extra td between columns and set a number of non-breaking spaces as @rene kindly suggested.

<table cellpadding="pixels"cellspacing="pixels"></table>
<td align="position"valign="position"></td>

cellpadding ="length in pixels" ~ The cellpadding attribute, used in the <table> tag, specifies how much blank space to display in between the content of each table cell and its respective border. The value is defined as a length in pixels. Hence, a cellpadding="10" attribute-value pair will display 10 pixels of blank space on all four sides of the content of each cell in that table.

cellspacing ="length in pixels" ~ The cellspacing attribute, also used in the <table> tag, defines how much blank space to display in between adjacent table cells and in between table cells and the table border. The value is defined as a length in pixels. Hence, a cellspacing="10" attribute-value pair will horizontally and vertically separate all adjacent cells in the respective table by a length of 10 pixels. It will also offset all cells from the table's frame on all four sides by a length of 10 pixels.

In most cases it could be better to pad the columns only on the right so just the spacing between the columns gets padded, and the first column is still aligned with the table.

CSS:

.padding-table-columns td
{
    padding:0 5px 0 0; /* Only right padding*/
}

HTML:

<table className="padding-table-columns">
  <tr>
    <td>Cell one</td>
     <!-- There will be a 5px space here-->
    <td>Cell two</td>
     <!-- There will be an invisible 5px space here-->
  </tr>
</table>

This can be achieved by putting padding between the columns using CSS. You can either add padding to the left of all columns except the first, or add padding to the right of all columns except the last. You should avoid adding padding to the right of the last column or to the left of the first as this will insert redundant white space. You should also avoid being too prescriptive with classes to specify which columns should have the additional padding as this will make maintenance harder if you later add a new column.

The ' lobotomised owl selector ' allows you to select all siblings, regardless of if they are a th , td or something else.

 tr > * + * { padding-left: 4em; }

 <table> <thead> <tr> <th>Column 1</th> <th>Column 2</th> <th>Column 3</th> </tr> </thead> <tbody> <tr> <td>Data 1</td> <td>Data 2</td> <td>Data 3</td> </tr> </tbody> </table>
