Numeric Table

Use required packages in setup/packages.tex

\usepackage{siunitx}  % Aligning numbers by decimal points in table columns
\usepackage{booktabs} % To thicken table lines
\usepackage{multicol} % split the legend into multiple columns
\usepackage{xcolor}   % to color columns
\usepackage{array}

Create mathematical symbols in math/symbols.tex

• Globally define column titles as macros to ensure consistent symbols throughout the document.

\newmathsnippet{\⟨symbol a⟩}{f_\mathrm{E}}
\newmathsnippet{\⟨symbol b⟩}{U_\mathrm{E}}
\newmathsnippet{\⟨symbol c⟩}{U_\mathrm{R,pp}}

• ⟨symbol a⟩, ⟨symbol b⟩, ⟨symbol c⟩: Column titles as mathematical expression
• ⟨data title⟩: File where the table’s body is stored
• ⟨placement specifiers⟩: see Float - Dynamically place figures, images, tables, and listings at the top, bottom, or single page
• ⟨caption⟩: Title displayed below the table and in the index
• ⟨table name⟩: Filename and handle to cross reference the table
• ⟨multicolumn header⟩ := column title that spans multiple columns
