If you have to insert a very long table, which takes up two or more pages in your document, use the longtable package. If you need more flexibility in the column layout, or to create a document with multiple columns, the package multicol provide a set of commands for that. Floating elements (tables and figures) can be inserted in a multicolumn document with wrapfig and wraptable. Tables are a fairly important part of LaTeX. Often you will want data to span multiple columns of the table, similar to colspan in HTML. In LaTeX it’s pretty easy too, using the. multicolumncolsformatcell_text.
For this purpose we created this online generator which (hopefully) will allow you to generate LaTeX code you can just copy & paste into your document’s source. Multi-line text in table cells — it is generated by putting another tabular environment inside a table cell.
