What Markdown is
A Markdown table is rows of pipe-separated cells with a dashed rule under the header. Alignment is set by placing colons in that rule.
README files, GitHub issues, documentation sites, Obsidian and Notion.
What LaTeX is
A LaTeX table is a tabular environment: a column specification, ampersands between cells and double backslashes at the end of each row.
Academic papers, theses and anything typeset with LaTeX or written in Overleaf.
What changes when you convert Markdown to LaTeX
Leading and trailing pipes are optional and both are handled. A pipe the author escaped with a backslash is read as data rather than a column break, which is the usual reason a hand-written table parses one column too wide.
Rules are drawn with booktabs by default, which is what most journal templates expect. The characters LaTeX treats as special, & % $ # _ { }, are escaped so a value like 50% compiles instead of ending the line.
What carries over from Markdown to LaTeX
One property of the Markdown has no home in LaTeX, and it is worth knowing which before you convert.
LaTeX is the end of the line for this data. Reading the table back out of it is a separate and much harder problem than writing it, so keep the Markdown if you will need the values again.
The identifier 007 comes out of the LaTeX as 007. Reading it as a number would have made it 7, and an id that changes value is worse than one that stays text.
The role "Analyst, data" survives with its comma, in one cell rather than split across two. That is the first thing to check in any converted table, and the usual place a LaTeX file goes wrong.
The quotes around Jonah "Jo" Pryce are left as a plain quote character in the LaTeX.
