How to create a matrix in Word with aligned columns?

Question

Word

I drew some matrix in Microsoft Word 2016.

This matrix turned out to be somewhat curved. That is, the top row (B1, B2, B3, B4, B5) turned out to be somewhat crowded relative to the lower columns of numbers.
I would like to get a matrix such that it has even columns of the numbers below:
1) 1st column: B1 - 1.8 - 3.45 - 2.5.
2) 2nd column: B2 - 0.43 - 1.455 - 0.3
3) 3rd column: B3 - 1.214 - 3.915 - 2.704
and so on.
PS In which case I am ready to use third-party programs, with further insertion of the matrix into Word.

Alexey Smirnov : Matrices are some kind of hell :) Even MathType can't cope with them :(
But try it, maybe it won't be crooked with your values.

Remove brackets, replace all separators with tabs, then select this entire "table" and choose - convert to table, tab delimiter. Then align as your heart desires, I now, according to your data, did it in 15 minutes, of which I was looking for "harmony" the most :D
