I have this slide that works fine.

format:
revealjs

## title
::: columns
::: {.column width="35%"}
```{.python code-line-numbers="2"}
def cal(C):
return 2 + C
```
:::
::: {.column width="10%"}
:::
::: {.column width="55%"}
```{python}
def cal(C):
res = 2 + C
return res
```
```{python}
#| echo: true
F = 0
def cal(C):
res = F + C
print('res', res)
return res
```
```{python}
print(F)
```

Now, I want to present the left column , then pause, then present the right column and pause before the result of print(F) appears.
I tried putting the . . . in order to pause but it seems it doesn't work when you have colunms defined.
