问题描述
有没有办法使用 manim
来显示和制作乳胶桌?
例如
\begin{table}[]
\centering
\begin{tabular}{lllll}
& & \multicolumn{2}{l}{End} & \\
Top & & Bottom & Bottom & \\
& Top & 40 & 160 & 200 \\
& Bottom & 640 & 160 & 800 \\
& & 200 & 800 & 1000
\end{tabular}
\end{table}
您在manim
会怎样?
from manimlib import *
import numpy as np
class TableManim(Scene):
def construct(self):
...
解决方法
如果你想直接用 LaTeX 来做它会是这样的:
class Table1(Scene):
def construct(self):
table = r"""
\begin{table}[]
\centering
\begin{tabular}{|l|l|l|l|l|}\hline
& & \multicolumn{2}{l}{End} & \\\hline
Top & & Bottom & Bottom & \\
& Top & 40 & 160 & 200 \\
& Bottom & 640 & 160 & 800 \\
& & 200 & 800 & 1000 \\\hline
\end{tabular}
\end{table}
"""
tex_table = TexText(table)
self.play(Write(tex_table))
但是,如果你想用 Manim 制作一个表格,它会有点复杂,它会是这样的(如果你需要它,你可以转换成一个函数)
class Table2(Scene):
def construct(self):
table = VGroup(*[
VGroup(*[
Text(f"{t}")
for t in row
]).arrange(DOWN,aligned_edge=LEFT)
for row in [
["Top"],["Top","Bottom"],["Bottom",40,640,200],160,800],[200,800,1000],]],)
table.scale(0.8)
BUFF = 0.5
rectangles = VGroup(*[
Rectangle(
width=mob.get_width()+BUFF,height=max(*[t.get_height() for t in table])+BUFF,).move_to(mob)
for mob in table
])
for t,r,align_direction in zip(table,rectangles,[UP,None,DOWN]):
if align_direction is not None:
t.align_to(r,align_direction)
t.shift(-align_direction*BUFF/2)
table_group = VGroup(*[
VGroup(t,r)
for t,r in zip(table,rectangles)
])
table_group.arrange(RIGHT,buff=0)
self.add(table_group)
