Strikethrough text in a Manim Table-CodePudding

Here is the source code of the documentation page of Table in Manim:

class TableExamples(Scene):
    def construct(self):
        t0 = Table(
            [["This", "is a"],
            ["simple", "Table in \n Manim."]])
        t1 = Table(
            [["This", "is a"],
            ["simple", "Table."]],
            row_labels=[Text("R1"), Text("R2")],
            col_labels=[Text("C1"), Text("C2")])
        t1.add_highlighted_cell((2,2), color=YELLOW)
        t2 = Table(
            [["This", "is a"],
            ["simple", "Table."]],
            row_labels=[Text("R1"), Text("R2")],
            col_labels=[Text("C1"), Text("C2")],
            top_left_entry=Star().scale(0.3),
            include_outer_lines=True,
            arrange_in_grid_config={"cell_alignment": RIGHT})
        t2.add(t2.get_cell((2,2), color=RED))
        t3 = Table(
            [["This", "is a"],
            ["simple", "Table."]],
            row_labels=[Text("R1"), Text("R2")],
            col_labels=[Text("C1"), Text("C2")],
            top_left_entry=Star().scale(0.3),
            include_outer_lines=True,
            line_config={"stroke_width": 1, "color": YELLOW})
        t3.remove(*t3.get_vertical_lines())
        g = Group(
            t0,t1,t2,t3
        ).scale(0.7).arrange_in_grid(buff=1)
        self.add(g)

I'm trying to strikethrough something. To do so I got inspired by this documentation page. Hence why, I've tried:

class TableExamples(Scene):
    def construct(self):
        t0 = Table(
            [['``<span strikethrough="true" strikethrough_color="red">This</span>``', "is a"],
            ["simple", "Table in \n Manim."]])
        t1 = Table(
            [["This", "is a"],
            ["simple", "Table."]],
            row_labels=[Text("R1"), Text("R2")],
            col_labels=[Text("C1"), Text("C2")])
        t1.add_highlighted_cell((2,2), color=YELLOW)
        t2 = Table(
            [["This", "is a"],
            ["simple", "Table."]],
            row_labels=[Text("R1"), Text("R2")],
            col_labels=[Text("C1"), Text("C2")],
            top_left_entry=Star().scale(0.3),
            include_outer_lines=True,
            arrange_in_grid_config={"cell_alignment": RIGHT})
        t2.add(t2.get_cell((2,2), color=RED))
        t3 = Table(
            [["This", "is a"],
            ["simple", "Table."]],
            row_labels=[Text("R1"), Text("R2")],
            col_labels=[Text("C1"), Text("C2")],
            top_left_entry=Star().scale(0.3),
            include_outer_lines=True,
            line_config={"stroke_width": 1, "color": YELLOW})
        t3.remove(*t3.get_vertical_lines())
        g = Group(
            t0,t1,t2,t3
        ).scale(0.7).arrange_in_grid(buff=1)
        self.add(g)

But it doesn't work. I've also tried using LaTeX tags, but Manim doesn't understand it as LaTeX because (I think?) this is interpreted as Text and not Tex. Any ideas?

CodePudding user response：

Take a look at the documentation of Table, you want to adapt the element_to_mobject keyword argument (because you are trying to use MarkupText syntax in a "normal" Text class, which does not work.

This does though:

class TableExamples(Scene):
    def construct(self):
        t0 = Table(
            [['<span strikethrough="true" strikethrough_color="red">This</span>', "is a"],
            ["simple", "Table in \n Manim."]],
            element_to_mobject=MarkupText)
        self.add(t0)
