I have a 2d array in the format

emi_309 | present | weak   | 6

emi_310 | present | strong | 9

emi_319 | present | medium | 8

emi_315 | present | weak   | 5

I want to check if a value exists in the first column using a simple function

E.g, check if emi_77 exists in the first column

I came across $.inArray(value, array) but this function is for a 1d array only.

Is there something similar for 2d array

Yes, if you do a combination of $.inArray and $.map:

if ($.inArray(value, $.map(arr, function(v) { return v[0]; })) > -1) {

    // ...

}
