Start with the meaning of each column
A course handout may contain tables copied from a PDF, a spreadsheet, or a photograph of a whiteboard. Before translating the layout into LaTeX, identify the header row, units, and any footnotes. A tidy table that mislabels a measurement is worse than an imperfect-looking one with the correct information.
Choose a simple structure
Use one column for each distinct variable and keep headings short. Avoid merging cells unless a grouped header is essential to understanding the data. Left-align words and use a consistent alignment for numbers. When a table becomes wider than the page, consider splitting it into smaller tables or moving a long explanation into the caption.
Check the source against the rendered page
After entering or converting the table, compile the document and compare every row with the original. Pay special attention to decimal points, minus signs, superscripts, and empty cells. If the input was a scan, zoom in on ambiguous characters rather than guessing. LaTeX compilation catches syntax problems; a human review catches changed values.
Give students a usable document
A worksheet should keep equations and tables editable for future corrections. Preserve the source file along with the compiled PDF, and put figures in an organized folder. This makes it easier to revise one exercise next semester without rebuilding an entire page from screenshots.
For educators starting with PDFs, photos, or Word pages, LaTeX conversion for students and researchers through styleLatex can produce editable source and a compiled preview. Its first five page conversions are free. Even with an automated starting point, inspect each table and equation before distributing the handout.
