| User   | I need to create a simple table with three columns and two rows. The header row should contain the titles "Name," "Age," and "City." The data row should have the values "John," "25," and "New York."                                                                                                                                                                                               |

## Example Output

Here's the LaTeX code to create a simple table with three columns and two rows, including a header row with the titles "Name," "Age," and "City," and a data row with the values "John," "25," and "New York":

```LaTeX  theme={null}
\begin{table}[h]
\centering
\begin{tabular}{|c|c|c|}
\hline
Name & Age & City \\
\hline
John & 25 & New York \\
\hline
\end{tabular}
\caption{Sample Table}
\label{tab:sample}
\end{table}

```

Explanation:

* The `table` environment is used to create a floating table that can be positioned automatically by LaTeX.
* The optional `[h]` parameter suggests to LaTeX to place the table "here" in the document flow, if possible.
* The `\centering` command centers the table horizontally on the page.
* The `tabular` environment is used to create the actual table structure.
* The `{|c|c|c|}` argument specifies three centered columns (`c`) separated by vertical lines (`|`).
* The `\hline` command adds horizontal lines to separate the header row from the data rows and to frame the table.
* The `&` character separates the cells within a row, and `\\` marks the end of a row.
* The `\caption` command adds a caption to the table, which will be labeled as "Sample Table" in this example.
* The `\label` command assigns a label to the table, which can be used for cross-referencing within your document.

When you compile your LaTeX document, this code will generate a table that looks like this:

```
+------+-----+----------+
| Name | Age |   City   |
+------+-----+----------+
| John |  25 | New York |
+------+-----+----------+

```
