Data is not displayed if column name has `[` or `]`

[statquant]

Hello, the following breaks for me when trying to render a data.table but not a data.frame:

reactable(data.frame(x=1:3, y=1:3))     

reactable(data.frame(x=1:3, `y_[]`=1:3))

reactable(data.table(x=1:3, `y_[]`=1:3))

Many thanks for the package

That's a good catch, thanks for the report. This is now fixed in the development version (https://github.com/glin/reactable/commit/f9b6c81de1fcede08e44b99e7cb6f828c06b1566):

• Columns with square brackets ([ or ]) in their column name now render correctly (#187).

Just for reference, the same is/was true for a tibble and likely any structure which preserves [ in column names.

data.frame typically converts names with make.names() so this didn't come up so easily with those, but is there any interest in preserving column names through reactable()?
