说明
tbl is a preprocessor for the groff/troff document formatting system that formats tables. It translates table descriptions embedded between .TS (table start) and .TE (table end) macros into troff formatting commands. Tables are defined with a format section specifying column alignment and a data section containing the content. Column classifiers include L (left), R (right), C (center), N (numeric alignment), and A (alphabetic). Modifiers like b (bold) and i (italic) can be applied to columns. Region options control table appearance: box draws a border, center horizontally centers the table, expand stretches it to fill the line width, and tab(c) sets the column separator character. tbl is typically invoked via groff -t rather than directly. When using multiple preprocessors, tbl should run before eqn (equations). The groff command handles ordering automatically.
