ng-model table show data angularjs

ng-model table show data angularjs

I ma very beginner in Angularjs and pardon my silly mistakes. I have a
table which shows data in three columns and i want to filter this table
based on a condition and hide unnecessary data in one column which
contains integers. I have used ng-show with some condition linked to
ng-model and this is working perfect if i enter data in my ng-model only
after loading total form. But, i want to show all the table data in the
beginning and then hide unnecessary data based on ng-show condition.
How can i do this? I am struggling!
<tr ng-show= "change > val1 " ng-repeat="change in montlyProjection();" >
<td>some data</td>
<td class="number">some data</td>
<td class="number"
ng-class="positiveNegative(convertToNumber(startBalance) +
change)">some data</td>
</tr>
</strong><input type="text" ng-model="val1" placeholder="Enter Amount" />
