Combining columns in a table into comma separated values while skipping NaN

I have many tables where I need to combine values that are not NaN from one column with another column, separated by commas.

The tables I have look like variations of this:

'2022_1_30_12_56_45_972' 0 0 NaN

'2022_1_30_12_56_48_783' 1 0 NaN

'2022_1_30_12_56_55_912' 2 0 2

'2022_1_30_12_57_2_446' 3 1 NaN

'2022_1_30_12_57_9_231' 4 1 NaN

'2022_1_30_12_57_12_990' 5 1 NaN

'2022_1_30_12_57_15_210' 6 1 NaN

What I want is this:

'2022_1_30_12_56_45_972' 0 0

'2022_1_30_12_56_48_783' 1 0

'2022_1_30_12_56_55_912' 2 0,2

'2022_1_30_12_57_2_446' 3 1

'2022_1_30_12_57_9_231' 4 1

'2022_1_30_12_57_12_990' 5 1

'2022_1_30_12_57_15_210' 6 1

I can loop through, find the values to combine, and combine them. But I can't get the 2 values into a single cell in a new table with only 3 columns. The code segment looks like:

for jj = 1:height(currTable)

        if isnan(currTable.Var4(jj))

        else
  
        currTable.Var3(jj) = strcat(num2str(currTable.Var3(jj)),',',num2str(currTable.Var4(jj)));

        end
    end

But when I try to combine the values into the third column, I get an error because the size of the new cell is 1x3.

Error using  . 
Unable to perform assignment because the left and right sides have a different number of elements.

Error in scratch (line 12)
        currTable.Var3(jj) = strcat(num2str(currTable.Var3(jj)),',',num2str(currTable.Var4(jj)));

currTable{jj} = strcat(num2str(currTable.Var3(jj)),',',num2str(currTable.Var4(jj)));

If you use cell arrays it becomes easier rather than putting them in numeric arrays
