I were tying to convert EPUB from following txt context with Markdown tables syntax:

**table 1**
First Header | Second Header
------------- | -------------
Content Cell | Content Cell
Content Cell | Content Cell


**table 2**
| Function name | Description |
| ------------- | ------------------------------: |
| `help()` | Display the help window. |
| `destroy()` | **Destroy your computer!** |

**table 3**
| Item | Value | t |
| --------- |: -----|
| Computer | \$1600 |
| Phone | \$12 |
| Pipe | \$1 |

but no table was shown in EPUB file successfully, the result was like this:

table 1 First Header | Second Header ––––- | ––––- Content Cell | Content Cell Content Cell | Content Cell

table 2 | Function name | Description | | ––––- | ––––––––––: | | help() | Display the help window. | | destroy() | Destroy your computer! |

table 3 | Item | Value | t | | ––– |: –—| | Computer | $1600 | | Phone | $12 | | Pipe | $1 |

What's wrong with the converting or syntax?
