How to extract specific data from data files?

I want to extract specific data from a table that I've transferred into Matlab. The table looks kind of like this.

id. dataa datab datac datad

--------- ----------- -------- ----------- --------

111 135 134 ... ...

111 143 176 ...

111 124 187

222 123 287

222 473 853

I specifically want to extract all the data for a specific id number.

I am also using an input statement to get the ID number for which I'm supposed to extract data.

So far I have something similar to

giveid = input('insert the ID for analysis: ');

Thank you for any help.

data = [111          135          134 
      111          143          176
      111          124          187
      222         123          287
      222          473          853]

data = 5×3

111 135 134 111 143 176 111 124 187 222 123 287 222 473 853

t = array2table(data)

t = 5×3 table
    data1    data2    data3
    _____    _____    _____

     111      135      134 
     111      143      176 
     111      124      187 
     222      123      287 
     222      473      853 

t.Properties.VariableNames = ["ID" "DataA" "DataB"]

t = 5×3 table
    ID     DataA    DataB
    ___    _____    _____

    111     135      134 
    111     143      176 
    111     124      187 
    222     123      287 
    222     473      853 

% giveid = input('insert the ID for analysis: '); 
giveid = 111 %You can use the line above instead

giveid = 111

t(t.ID==giveid,:)

ans = 3×3 table
    ID     DataA    DataB
    ___    _____    _____

    111     135      134 
    111     143      176 
    111     124      187
