Can anyone please give an advice how to set the significant numbers only on the table numerical fields?
Code:
clc;
clear all;
xID = ['1';'2';'3';'4';'5'];
xName = {'Sun';'Moon';'Jupiter';'Earth';'Venus'};
I1 = [1.1112;9.2311245;3.341145;6.341122;54.211155];
I2 = [1.1199999;1.1211345;1.881188;1.5781188;1.63711777];
I3 = [6.232114;5.1211223654;4.452112272;3.5711235;2.62112247];
mt = table(xID, xName, I1, I2, I3);
table_data=cellfun(@(x) sprintf('%0.2f', x), mt), 'UniformOutput',0);

I wish to show it using matlab report and not for display issues.

What, specifically, do you mean by " using matlab report"?

This example shows how to permanently round the data to 2dp which is usually undesirable but if you're printing it to a report, it's not like the level of precision can be edited anyway.
Use varfun to determine which columns are numeric.
colIsNum = varfun(@isnumeric, mt,'OutputFormat','uniform')
ans =
1×5 logical array
0 0 1 1 1
table_data = mt; % keep original, more precise data
table_data{:,colIsNum} = round(mt{:,colIsNum},2)
table_data =
5×5 table
xID xName I1 I2 I3
___ ___________ _____ ____ ____
1 {'Sun' } 1.11 1.12 6.23
2 {'Moon' } 9.23 1.12 5.12
3 {'Jupiter'} 3.34 1.88 4.45
4 {'Earth' } 6.34 1.58 3.57
5 {'Venus' } 54.21 1.64 2.62
