How to draw checkbox or tick mark in GitHub Markdown table?

Try adding a - before the [] or [x]. That's an - followed by a blank space .

Below is an example from Github blog.

### Solar System Exploration, 1950s – 1960s

- [ ] Mercury
- [x] Venus
- [x] Earth (Orbit/Moon)
- [x] Mars
- [ ] Jupiter
- [ ] Saturn
- [ ] Uranus
- [ ] Neptune
- [ ] Comet Haley

It appears like below:

Here's how one could do the same in a table:

| Task           | Time required | Assigned to   | Current Status | Finished | 
|----------------|---------------|---------------|----------------|-----------|
| Calendar Cache | > 5 hours  |  | in progress | - [x] ok?
| Object Cache   | > 5 hours  |  | in progress | [x] item1<br/>[ ] item2
| Object Cache   | > 5 hours  |  | in progress | <ul><li>- [x] item1</li><li>- [ ] item2</li></ul>
| Object Cache   | > 5 hours  |  | in progress | <ul><li>[x] item1</li><li>[ ] item2</li></ul>


- [x] works
- [x] works too

Here's how it looks:

Now emojis are supported! :white_check_mark: / :heavy_check_mark: gives a good impression and is widely supported:

Function | MySQL / MariaDB | PostgreSQL | SQLite
:------------ | :-------------| :-------------| :-------------
substr | :heavy_check_mark: |  :white_check_mark: | :heavy_check_mark:

renders to (here on older chromium 65.0.3x) :

I used ☐ (☐) for [ ] and ☑ (☑) for [x] and it works for marked.js which says it is compatible with Github markdown. I based my solution on answers for this question. See also this informative answer.

Update: I should have mentioned that when you do it this way, you do not need the <ul>, e.g:

| Unchecked | Checked |
| --------- | ------- |
| ☐   | ☑ |

You can use emojis

Done? | Name
:---:| ---
⬜️| Nope
✅| Yep

|checked|unchecked|crossed|
|---|---|---|
|✓|_|✗|

checked unchecked crossed ✓ _ ✗

Where

✓ via HTML Entity Code
✗ via HTML Entity Code
_ via underscore character
and table via markdown table syntax.

There are very nice Emoji icons instructions available at

or at https://github.com/StylishThemes/GitHub-Dark/wiki/Emoji

You can check them out. I hope you would find suitable icons for your writing.

Best,

Unfortunately, the accepted answer doesn't work for me (I'm using GitHub flavoured markdown).

It occurs to me since we're adding HTML elements, why not just add an <input> instead.

| demo                                              | demo |
| ------------------------------------------------- | ---- |
| <input type="checkbox" disabled checked /> works  |      |
| <input type="checkbox" disabled /> works here too |      |

This should work in any environment cuz it's plain HTML (see FYI below).

FYI, this example was tested in VS Code markdown preview mode(GitHub flavoured), the screenshot is also taken in VS Code preview mode. It's not working on GitHub.

Emoji mentioned above is a good alternative, if this doesn't work in your target environment.

If you have an issue with the standard markdown code. You can use emojis.

Native Github

If you are using GitHub's default emojis, you can use these. Something to note is that there is no uncheck, so you have to use different emojis to get that look.
