| Problem | Cause | Fix |
|---|---|---|
| Vertical lines | Using ` | ` in column spec |
\hline | Old habit | Use \toprule/\midrule/\bottomrule |
| Table too wide | Too many columns | Use tabularx with X columns, or \resizebox |
longtable in table | Incompatible | longtable replaces table environment |
\multirow misaligned | Row height differences | Add \rule{0pt}{2.5ex} or adjust manually |
S column header error | Text in S column | Wrap header in {...} |
| Footnotes in table | \footnote fails in tabular | Use \tablefootnote (tablefootnote pkg) or threeparttable |
booktabs + colortbl gaps | Rules have gaps with color | Add \abovetopsep=0pt or use \arrayrulecolor |
\toprule, \midrule, \bottomrule — almost never need more\addlinespace to group rows visually instead of extra rules\caption above the table (convention for tables, unlike figures)\small or \footnotesize before tabular to shrink wide tablesthreeparttable package for proper table footnotes\arraystretch to adjust row height: \renewcommand{\arraystretch}{1.2}
