我有一个包含各种值的数据表。它包括以下各列：

| Value 1 | Value 2 |
|---------|---------|
|0        |235      |
|1        |123      |
|1        |309      |
|1        |540      |
|2        |34       |
|3        |123      |
|3        |959      |
|3        |3939     |

我想要一个包含Value 2的表，具体取决于Value 1的每个值。它看起来是这样的：

| Value 1 | Value 2        |
| --------|----------------|
| 0       |[235]           |
|1        |[123, 309, 540] |
|2        |[34]            |
|3        |[123, 959, 3939]|

或者类似的东西。
我尝试了几种解决方案，例如：

t = table;
    for i=1:length(existing_table)  
        t(existing_table, end+1) = existing_table.value2(i) % append to case i
    end;
    
    --> returns Error using  () 
    Right hand side of an assignment into a table must be another table or a cell array.
    
    --------------
    t = table;
    for i=1:length(existing_table)  
        switch existing_table.value2(i) 
            case 0
               t(0, end+1) = existing_table.value2(i) % append to case 
    0
        % etc...
        end;
    end;
    
    
    --> returns Error using  () 
    Right hand side of an assignment into a table must be another table or a cell array.
    --------------

    t = table;
    t.v1 = value1;
    t.v2 = unique(value2) % Does not return the kind of table that I would like
