If you search for an AI table generator, you will find a lot of tools
that generate something vaguely table-shaped and call it done. The
output is usually wrong in ways that are annoying to fix: misaligned
columns, no column types, no export that is actually usable.

The features worth caring about in a table builder are less about AI
and more about the fundamentals: does it understand what kind of data
is in each column, does the export look right, and does it stay out
of the way while you work?

Column types are the first thing to look for. A tool that treats every
cell as a string will right-align a currency column in the output or
format 84.1 as 84.10000000001. A tool that understands column types (Text, Number, Currency, Percentage, Date) will format values correctly
and generate proper alignment in LaTeX exports automatically.

Export quality is the second thing. A PDF export that looks like a
screenshot of a spreadsheet is not useful. The output should be clean
enough to hand to a client or include in a paper without manual cleanup.
LaTeX export should generate a complete tabular environment, not just
the cell values separated by ampersands.

Smart paste is the third thing most people discover late. If you have
data in Excel or Google Sheets, you should be able to copy the cells
and paste directly into a table builder. This works because Excel writes
tab-separated data to the clipboard when you copy a range. A good table
builder reads that and reconstructs the table automatically.

I built Tablesmit with all of this in mind. It is free, open source,
and MIT licensed.
