AngularJS dynamic table using 2x2 array data using ng-repeat

I have a json structure which I am trying to bind to a table and i'm trying to do the best I can to use ng-repeats to avoid boilerplate code.

My json structure is as follows:

{ 
    "data": {
        "field1": 2809,
        "field2": {
            "10": [1, 2, 3, 4, 3, 0, 0, 0, 0],
            "20": [2, 3, 4, 5, 6, 7, 8, 9, 0],
            ....
            "100": [2, 3, 4, 5, 6, 7, 8, 9, 0]
}

I am trying for this to autogenerate in such a way that my table appears like this

Field0 Field1 Field2 Field3 Field4 Field5 Field6 Field7 Field8 Field9 Field10
-----------------------------------------------------------------------------
10     1       2      3      4      3      0      0     0      0         13
20     2       3      4      5      6      7      8     9      0         44
...
100    2       3      4      5      6      7      8     9      0         44

I am not sure how to get the ng-repeats for this to work

Here is a sample markup I am using

<tr ng-repeat="nums in tabData.field2">
    <td ng-repeat="num in nums">
        {{ num[$index] }}
    </td>
</tr>

The table is completely broken if I do this and I only get [1, 2 ... 0] in a single row. I am not sure how I can get this to work if I can get this to work.

I get this error

angular.js:15536 Error: [ngRepeat:dupes]

var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
  $scope.tabData = {
    "data": {
      "field1": 2809,
      "field2": {
        "10": [1, 2, 3, 4, 3, 0, 0, 0, 0],
        "20": [2, 3, 4, 5, 6, 7, 8, 9, 0],
        "100": [2, 3, 4, 5, 6, 7, 8, 9, 0]
      }
    }
  };
});
td input {
  width: 35px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.7.5/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">
  <table>
    <tr>
      <td ng-repeat="head in tabData.data.field2['10'] track by $index">
        Field{{ $index + 1 }}
      </td>
    </tr>
    <tr ng-repeat="(row,col) in tabData.data.field2 track by $index">
      <td ng-repeat="field in col track by $index">
        <input ng-model="tabData.data.field2[row][$index]" value="{{field}}" type="text" />
      </td>
    </tr>
  </table>
  <span>{{tabData}}</span>
</div>
