BUG: xlsxwriter does not handle vertical-align: middle

[tehunter]

Pandas version checks

• I have checked that this issue has not already been reported.

• I have confirmed this bug exists on the latest version of pandas.

• I have confirmed this bug exists on the main branch of pandas.

Reproducible Example

import pandas as pd

df = pd.DataFrame({"A": [0, 1, 2]}, index=pd.MultiIndex.from_product([["Merged"], ["x", "y", "z"]]))

# Expected
with pd.ExcelWriter("temp1.xlsx", engine="openpyxl") as writer:
    styled.to_excel(writer)

# Unexpected
with pd.ExcelWriter("temp2.xlsx", engine="xlsxwriter") as writer:
    styled.to_excel(writer)

Issue Description

Exporting a DataFrame styled with "vertical-align: middle" does not produce expected output with xlsxwriter engine.

With openpyxl (expected behavior):

With xlsxwriter:

The error arises from xlsxwriter expects the vertical align property to be "vcenter", while openpyxl expects "center". The _xlsxwriter._XlsxStyler should translate "center" to "vcenter" for the valign property.

Expected Behavior
