Based on this link pgfplotstable; longtable with caption and repeating header

I wrote this MWE:

documentclass{article}

usepackage{longtable}

usepackage{booktabs}

usepackage{multirow}

usepackage{pgfplotstable}

%%% Code from Dr. Christian ------ for not using headers.----------------------

pgfkeysifdefined{/pgfplots/table/output empty row/.@cmd}{

    % upcoming releases offer this more convenient option:

    pgfplotstableset{

        empty header/.style={

          every head row/.style={output empty row},

        }

    }

}{

    % versions up to and including 1.5.1 need this:

    pgfplotstableset{

        empty header/.style={

            typeset cell/.append code={%

                ifnumpgfplotstablerow=-1 %

                    pgfkeyssetvalue{/pgfplots/table/@cell content}{}%

                fi

            }

        }

    }

}

But the result is:

Is possible to break line arbitrarily?

How can I improve the code to obtain something like this:
