I have a text file shown below. The file has .vasp extension.
When I changed the extension to .txt, the file is opening by entering readtable('filename.txt'), could you please help me open this file without changing extension to .txt ?

Use detectImportOptions to tell readtable to read the file as a text file.
One recent example from an earlier Answer:
opts = detectImportOptions('breast-cancer-wisconsin.data', 'FileType','text');
BCTable = readtable('breast-cancer-wisconsin.data', opts);
A similar approach should also work for your files.
See Text and Spreadsheet Files in the readtable documentation for more information.
