    Why are you nesting a tabular inside the tabularx and the tabularx inside a resizebox? Commented Nov 21, 2018 at 7:43

    never put tables in \resizebox{\textwidth}{!}{ it just produces inconsistent font sizes (as well as if you have a linebreak after { a sprurious space on the left). If you want help with an error please provide a complete but small test file, no one can run your fragment as posted but remove the inner tabular a s currently everything is in a one-row one column tabularx Commented Nov 21, 2018 at 7:54

The posted code (if completed to a document) does not give the error in the title, it runs without error but with the warning

LaTeX Warning: `!h' float specifier changed to `!ht'.

However it is a one-row one column table with a nested table in that cell
