@Tag { aligned }
@Begin
@PP
Columns of numbers are often presented with decimal points aligned:
aligned. @Index { aligned columns in tables }
@CD @Tab
@Fmta { @Col A }
{
@Rowa A { 5^.46 }
@Rowa A { 3^.4159 }
@Rowa A { 5772^ }
}
You can produce this by placing a @Code "^" symbol just before the
alignment point in each entry:
@ID @OneRow @Code {
"@Tab"
" @Fmta { @Col A }"
"{"
" @Rowa A { 5^.46 }"
" @Rowa A { 3^.4159 }"
" @Rowa A { 5772^ }"
"}"
}
The equals signs of equations can be aligned in the same way. The
format of such columns should not contain @Code "@CC" or {@Code "@RR"}.
@PP
The simplest way to get a heading over an aligned column is to use the
@Code "^" symbol in the heading as well. If it is not possible to do
this, for example because the heading entry is a paragraph of text
broken over more than one line, the most viable alternative is to use
@Code "@Over" in the heading line's format to make the heading column
span over the aligned column:
@ID @OneRow @Code {
"@Tab"
" @Fmta { @Col @CC H @Over A }"
" @Fmtb { @Col A }"
"{"
" @Rowa H { Heading }"
" @Rowb A { 5^.46 }"
" @Rowb A { 3^.4159 }"
" @Rowb A { 5772^ }"
"}"
}
for example produces
@CD @Tab
@Fmta { @Col @CC H @Over A }
@Fmtb { @Col A }
{
@Rowa H { Heading }
@Rowb A { 5^.46 }
@Rowb A { 3^.4159 }
@Rowb A { 5772^ }
}
Unfortunately, the aligned entries are left-justified in the column,
not centred.
