The Markdown
table does not support cell merge by default, so you should use HTML
table.
And in comment, you said
"Even this time the image took only one row, ..."
in this case just use rowspan
.
<table>
<tr>
<td>- Identifying cutomer needs (requirments)</td>
<td rowspan="11">
<img src="https://user-images.githubusercontent.com/74305823/118094261-783e8280-b409-11eb-8f50-8ed0b304fef0.png" width="300"/>
</td>
</tr>
<tr>
<td>- market analysis (requirements)</td>
</tr>
<tr>
<td>- defining goals (requirements)</td>
</tr>
<tr>
<td>- Establishing functions (Prodct concept)</td>
</tr>
<tr>
<td>- Task Specifications (Prodct concept)</td>
</tr>
<tr>
<td>- Conceptualizatoin (Solution concept)</td>
</tr>
<tr>
<td>- Evaluating Alternatives</td>
</tr>
<tr>
<td>- Emnodiment Design</td>
</tr>
<tr>
<td>- Analysis and Optimization</td>
</tr>
<tr>
<td>- Experiment</td>
</tr>
<tr>
<td>- Marketing</td>
</tr>
</table>
EDIT
AS @tarleb said, using <ul>...</ul>
tag can be more simple.
<table>
<tr>
<td>
<ul>
<li>Identifying cutomer needs (requirments)</li>
<li>market analysis (requirements)</li>
<li>defining goals (requirements)</li>
