Available in rust_xlsxwriter
>= v0.40.0.
I've started work on supporting worksheet tables.
Tables in Excel are a way of grouping a range of cells into a single entity that has common formatting or that can be referenced from formulas. Tables can have column headers, autofilters, total rows, column formulas and default formatting.
See the Python docs for details: https://xlsxwriter.readthedocs.io/working_with_tables.html
Here is an example of one of the tables generated by the example program below.
There is still work to do on parameter validation, documentation and some minor features. It also doesn't currently support cell formatting. That will have to wait for a subsequent release.
