How to hide columns in HTML table?_问答_开发者

I have created a table in ASPX. I want to hide one of the columns based on the requirement but there is no attribute like visibl开发者_如何学Goe in the HTML table building. How can I solve my problem?

You need to use Style Sheet for this purpose.

<td style="display:none;">

You can use the nth-child CSS selector to hide a whole column:

#myTable tr > *:nth-child(2) {
    display: none;
}

This works under assumption that a cell of column N (be it a th or td) is always the Nth child element of its row.

Here's a demo.

If you want the column number to be dynamic, you could do that using querySelectorAll or any framework presenting similar functionality, like jQuery here:

$('#myTable tr > *:nth-child(2)').hide();

Demo with jQuery

(The jQuery solution also works on legacy browsers that don't support nth-child).

you can also use:

<td style="visibility:hidden;">
or
<td style="visibility:collapse;">

The difference between them that "hidden" hides the cell but it holds the space but with "collapse" the space is not held like display:none. This is significant when hidding a whole column or row.

Kos's answer is almost right, but can have damaging side effects. This is more correct:

#myTable tr td:nth-child(1), #myTable th:nth-child(1) {
    display: none;
}

CSS (Cascading Style Sheets) will cascade attributes to all of its children. This means that *:nth-child(1) will hide the first td of each tr AND hide the first element of all td children. If any of your td have things like buttons, icons, inputs, or selects, the first one will be hidden (woops!).

Even if you don't currently have things that will be hidden, image your frustration down the road if you need to add one. Don't punish your future self like that, that's going to be a pain to debug!

My answer will only hide the first td and th on all tr in #myTable keeping your other elements safe.

Bootstrap people use .hidden class on <td>.

You can also hide a column using the col element https://developer.mozilla.org/en/docs/Web/HTML/Element/col

To hide the second column in a table:

<table>
  <col />
  <col style="visibility:collapse"/>
  <tr><td>visible</td><td>hidden</td></tr>
  <tr><td>visible</td><td>hidden</td></tr>

Known issues: this won't work in Google Chrome. Please vote for the bug at https://bugs.chromium.org/p/chromium/issues/detail?id=174167

<style>
.hideFullColumn tr > .hidecol
{
    display:none;
}
</style>

use .hideFullColumn in table and .hidecol in th.You don't need to add class in td individually as it will be problem because index may not be in mind of each td.

You can also do what vs dev suggests programmatically by assigning the style with Javascript by iterating through the columns and setting the td element at a specific index to have that style.

<!doctype html>
<html lang="en">
<head>
<style id="myStyleSheet">
...
</style>

var column = 3;
var styleSheet = document.getElementById("myStyleSheet").sheet;
var rule = "table  tr td:nth-child("+ column +"),table th:nth-child("+ column +") 
{display: none}";
styleSheet.insertRule(rule);

Here is the another solution to hide dynamically a column

define class for both th and td of the column to hide

<table>
   <tr>
     <th> Column 1 </th>
     <th class="dynamic-hidden-col"> Column 2 </th>
     <th Column 3 </th>
  </tr>
  <tr>
     <td> Value 1 </td>
     <td class="dynamic-hidden-col"> Value 2 </td>
     <td> Value 3 </td>
  </tr>
     <td> row 2 Value 1 </td>
     <td class="dynamic-hidden-col"> row 2 Value 2 </td>
     <td> row 2 Value 3 </td>
  <tr>
</table>

Here is the Jquery script for hide column.

$('#hide-col').click(function () {      
    $(".dynmic-hidden-col").hide();
});

This way the table column can be hidden dynamically.
