[Tex/LaTex] How to align a vertical line at the end of the multicolumn in a table

horizontal alignmentmulticolumntables

How to align this vertical line at the end of the multi-column?

I searched, but I could not find an answer for such problem. This was originated from How to fix this Package array Error: Only one column-spec allowed?

Update 1

I find another question which seems to have the same problem, but it is not easy to understand what they did to fix it. I have to open my diff program to compare the original code and the fixed code:

  1. Why are the lines around my multicolumn cell misaligned?

On the right there is the fixed code, on the left is the original code.

That table goes from this:

Into this:

Update 2

By @David Carlisle comment, I find out that the question mentionated on the Update 1 is different from this one:

the edited question is an entirely different issue, please don't change the question that way invalidating all posted answers. The added question is the common issue of putting | on the wrong side of the cell boundary, the original question is unrelkated to that and just about your mis-use of

Your preamble has obscured the necessary column spec:

        *1{@{\hspace{3.0pt}}>{ \RaggedRight\arraybackslash\hsize=1.1\hsize }p{1.9cm}|} % Quantidade
        *1{@{\hspace{3.0pt}}>{ \RaggedRight\arraybackslash\hsize=1.1\hsize }p{3.0cm}|} % Valor
        *1{@{\hspace{3.0pt}}>{ \RaggedRight\arraybackslash\hsize=1.1\hsize }p{2.6cm}|} % Valor
    }

        \hline Item &   Quantidade  &   Valor Unitário (R\$) & Valor Total (R\$) \\ \hline
        Total       & \multicolumn{2}{c|@{\hspace{3.0pt}}}{}                  & 165,00            \\ \hline

    \end{tabular}

\end{document}

I left in the \hsize=1.1\hsize but it is completely wrong! Also as commented under the question, the @ usage here is making the vertical rules no longer centred in the inter-column space.
