@Section @Title { Margins } @Begin @PP @Code "@Tab" places a @I { vertical margin } above and below each row, and a margins.tables @SubIndex { in tables } @I { horizontal margin } to the left and right of each column. (If there are no side rules, the leftmost and rightmost margins are omitted.) The size of these margins is determined by two options to the @Code "@Tab" symbol: @ID @OneRow @Code { "@Tab" " hmargin { 0.3c }" " vmargin { 0.2v }" " @Fmta { ... }" "..." } Shown here are the default values, 0.3 centimetres for the horizontal margins, and 0.2 times the current inter-line spacing (denoted by the letter {@Code v}) for the vertical margins. @PP The horizontal margin is fixed, but each row may have its own vertical margin: @ID @OneRow @Code { "@Rowa" " vmargin { 0.5vx }" " A { ... }" } If omitted, the @Code vmargin value is taken from the @Code "@Tab" option. @PP The value shown here, {@Code "0.5vx"}, requests a vertical margin of half the current inter-line spacing, measured from the baseline of the entry rather than from its edge (this is what the @Code x means). This value is a good choice when the entries contain simple words or lines of text (i.e. no paragraphs, large equations, figures, etc.): @CD { @Tab vmargin { 0.5vx } @Fmta { @Col @Heading A ! @Col @Heading B } @Fmtb { @Col A ! @Col @CC B } { @Rowa A { Course } B { Enrolment } @Rowb A { Software Engineering } B { 174 } @Rowb A { Complexity Theory } B { 37 } } } since the lines of the table will then be separated evenly like the lines in paragraphs. @End @Section
