Elsevier CAS Double Column

The Elsevier CAS sample tables use booktabs rules (\toprule, \midrule, \bottomrule), but the booktabs package must be loaded in your preamble: add \usepackage{booktabs}. If it still fails, your local TeX installation is missing booktabs — on LetX the full TeX Live is preinstalled, so the template compiles without extra setup.

They are the two layouts of the Elsevier CAS (Complex Article Suite) class: cas-sc.cls is single-column and cas-dc.cls is double-column. Check the journal’s Guide for Authors — single-column (cas-sc) is often requested for review, while double-column (cas-dc) matches most final published layouts.
