 Regular Markdown syntax is not processed within code blocks. E.g.,
 asterisks are just literal asterisks within a code block. This means
 it's also easy to use Markdown to write about Markdown's own syntax.

 ### Tables
 
-| Column 1       | Column 2     | Column 3       |
+Markdown tables are created using pipes (|) to separate columns and hyphens (-) to define the header row. Here’s the basic structure:
-| :------------- | :----------: | -----------:   |
+
-|  Cell Contents | More Stuff   | And Again      |
+1. Header Row: The first row contains column names.
-| You Can Also   | Put Pipes In | Like this [\|] |
+2. Divider Line: The second row uses hyphens to separate the header from the data.
+3. Data Rows: The rows below the divider contain the actual data.
+
+| Name  | Age |  City    |
+|-------|-----|-------|
+| Alice | 25  | New York |
+| Bob   | 30  | London   |
+
+You can style text inside Markdown table cells just like regular Markdown.
+This includes making text bold, italic, monospaced, or adding links or code.
 
 Column 1 | Column 2 | Column 3
 --- | --- | ---
 **Things** | _Don't_ | [Need](/)
 To | *__Look__* | `Pretty`
 
+You can align text in Markdown table columns to the left, right, or center by placing a colon (:) in different positions within the header divider row.
+
+1. Left-aligned: `:---` (Colon on the left)
+2. Right-aligned: `---:` (Colon on the right)
+3. Center-aligned: `:---:` (Colons on both sides)
+
+| Column 1       | Column 2     | Column 3       |

+|  Cell Contents | More Stuff   | And Again      |
+| You Can Also   | Put Pipes In | Like this [\|] |
+
+Markdown tables don’t support merging cells (like in HTML).
+Each cell is treated separately.
+But if you want an empty space, just leave it blank.
