How to split Table header into 2 lines

I have a table with a long header text

I tried to split the header into 2 rows but I got an error in the Tex when I added

Here is my tex

begin{table*}[htbp]
    caption{AutoML platforms used in the healthcare research}
    begin{center}
        begin{tabular}{|c|c|c|c|c|c|c|c|}
            hline
            textbf{textit{Research}} & textbf{{Commercial AutoML (Google AutoML and Apple Create ML)}}&  textbf{textit{T1}}& textbf{textit{T2}}& textbf{textit{T3}}
            & textbf{textit{T4}}& textbf{textit{T5}}
            & textbf{textit{T6}}
            hline
            [36]&.&.&.&.&.&.&X
            hline          
            [37]&.&.&.&.&.&.&X
            hline

            
        end{tabular}
        label{graph_i}
    end{center}
end{table*}

Is there a way to break the header into to 2 lines?

Thanks

   textbf{textit{Research}} & textbf{thead{Commercial AutoML (Google AutoML and Apple Create ML)}}&  textbf{textit{T1}}& textbf{textit{T2}}& textbf{textit{T3}}
