I have the following table:
#align(
center,
table(
// fill: (x, y) =>
// if x == 5 and y in (0, 4) {
// red.lighten(70%)
// },
columns: range(7).map(n => auto),
inset: (x: 0.5em, y: 0.5em),
align: horizon,
stroke: none,
[Basis], [$x_1$], [$x_2$], [$s_1$], [$s_2$], [$s_3$], [$b$],
table.hline(),
[$s_1$], [0], [1], [1], [-1], [0], [2],
[$x_1$], [1], [0], [0], [1], [0], [2],
[$s_3$], [0], [1], [0], [0], [1], [3],
table.hline(),
[$z$], [0], [-2], [0], [3], [0], [6],
)
)
I would like to draw a labelled curved arrow to the right of the table to describe row operations. For example, if the row operation is given by $R_1 = R_1 + 3R_3$, then the arrow should start at row 3 and end at row 1.
