# Problems with long table and formatting problems

I have made this table and I would like to know how to merge the entries 'Set flow rate','Q_{set}' and 'Experimental parameters' into one cell so that I don't repeat it.

Secondly, how do I keep the numbers aligned in the columns 'Batch 1' and 'Batch 2' while cutting all the extra space I have on the left (I am trying not to let the table exceed the page space)?

Then how can I increase the height of the rows so then the units in the last column are not cut off?

I would also like to know how to center the numbers or words in the cell, since at the moment they occupy only the upper part of each cell.

Lastly, I would like to make these three tables a big table that breaks when the page is full. I tried to implement the package longtable without succeeding.

Based on the partial answer of user @MichaelPalmer let us have a look to the second part of answer, the usage of longtable and the too big space left of the numbers ...

Your code uses siunitx to format the numbers and the space of the table columns (S). Therefore you can add table-format = +1.4e+4 to \sisetup to get one number before the dezimal point, 4 after it (+1.4) and for the exponent use 4 characters (e+4). Now you can get a smaller width for a column with S[table-column-width=3cm].

All this changes you will find in the following part of code:

\begin{table}[!ht]

\small\sisetup{per-mode=symbol,table-format = +1.4e+4} % 1 integer,4 dezimal 4 exponent
%                                ^^^^^^^^^^^^^^^^^^^^^^
\setlength{\doublerulesep}{5pt}
\rowcolors{3}{LightMauve}{MyWhite}
\begin{tabular}{|>{\centering}p{3.5cm}||%
>{\centering}p{1.5cm}|%
S[table-column-width=4cm]|%
S[table-column-width=3cm]|% <========================
S[table-column-width=2cm]|}
\hhline{~----}


To be able to use environment longtable you can use the following code to start the longtable:

{ \small\sisetup{per-mode=symbol,table-format = +1.4e+4} % 1 integer,4 dezimal 4 exponent
\setlength{\doublerulesep}{5pt}
\rowcolors{3}{MyWhite}{LightMauve}
\begin{longtable}{|>{\centering}p{3.5cm}||
>{\centering}p{1.5cm}|
S[table-column-width=4cm]|
S[table-column-width=3cm]| % <=======================

\toprule
\toprule
\midrule
\multicolumn{5}{c}{to be continued ...} \\
\midrule
\endfoot
\bottomrule
\endlastfoot


and

\end{longtable}
}


to end it. See that the closing bracket is needed to close the group I started to have fontsize small and the sisetup only available for longtable.

you get the results:

for the first table and

for the start of the longtable ...

Please see that the column for Batch2 is smaller (3cm) than the column for batch1 (4cm).

A partial answer only. I have replaced the column specifiers with p, and the \dfrac macros for the units with \nicefrac from package nicefrac, which reduces the height. I have removed the \linespread setting and instead increased \arraystretch, which increases the space between table rows, but not the interline distance within. I have commented out all table-related packages that are not used in the current version of the code.

Your request to merge table cells with identical contents doesn't mesh too well with the use of alternating row colors. If you want to keep the latter, I would suggest to just fill the repeating cells with something like ".

I haven't tried to fix the horizontal alignment within the cells. The docs of the dcolumn package aren't that straightforward, and I need to attend to my day job now.
