Hi Neha,
Greetings from Syncfusion support.
Based on your query, when you are
rendering the grid, the alignments of the gridlines are not proper in your
grid. We have prepared a sample using React, but the issue is not reproduced.
Find the sample below.
Sample: https://stackblitz.com/edit/react-7mdh2f?file=index.js,index.html
If you still face the issue please share a simple sample to
replicate the issue or try to reproduce the issue in the shared sample.
Regards,
Joseph I.
