To effectively showcase your data in the desired format, it may be best to reorganize your data within the JS code before attempting to display it.
Attempting to match user names when they are spread across different objects in the data array can be quite complex.
I recommend handling the processing of your scope.data in the controller (assuming limited control over how the data is received).
After fetching your data...
$scope.data = [
{
date:'1-1-2016',
users:[
{
'name':'james',
'mark':18
},
{
'name':'alice',
'mark':20
}
]
},
{
date:'2-1-2016',
users:[
{
'name':'james',
'mark':60
},
{
'name':'alice',
'mark':55
}
]
}
]
var userData = {};
var possibleDates = [];
for (dataObj of Object.entries($scope.data)) {
for (userObj of dataObj) {
if ( !userData[userObj.name] ) {
userData[userObj.name] = {};
}
userData[userObj.name][dataObj.date] = userObj.mark;
if (dates.indexOf(dataObj.date) < 0) {
dates.push(dataObj.date);
}
}
}
$scope.users = userData;
$scope.dates = possibleDates;
This will result in an object like this within your scope
$scope.users = {
'james': {
'1-1-2016': 18,
'2-1-2016': 60
},
'alice': {
'1-1-2016': 20,
'2-1-2016': 55
}
};
$scope.dates = ['1-1-2016', '2-1-2016'];
This structure appears more suitable for your template. However, it assumes each user has a corresponding entry for every date.
<div>
<div id='header-row'>
<div id='empty-corner></div>
<div class='date-header' ng-repeat='date in $scope.dates></div>
</div>
<div class='table-row' ng-repeat='{key, value} in $scope.users'>
<div class='user-name'>{{ key }}</div>
<div class='user-data' ng-repeat='date in $scope.dates>
{{ value[date] }}
</div>
</div>
</div>
If you apply inline-block styles to the rows/elements, this setup should provide the desired outcome.
Alternatively, consider simplifying your data further by consolidating user information into arrays rather than using objects with date keys.
