tabularx inside tcolorbox not centered properly












12















I am trying to put a tabularx inside a tcolorbox but it's not centered properly, it's shifted slightly to the right. Here is the code I am using. I am using figure environment for the caption. Is there a better way to do this?



documentclass[12pt, a4paper]{article}
usepackage[top=1in, bottom=1.5in, right=1in, left=1in]{geometry}
usepackage{tabularx}
usepackage{tcolorbox}
usepackage{chemfig}

newcolumntype{Y}{>{centeringarraybackslash}X}

begin{document}

begin{figure}[ht]

begin{tcolorbox}
begin{tabularx}{1linewidth}{YYYY}
{}chemfig{C(-[:90,.6]H)(-[:180,.6]H)(-[:270,.6]H) -[,.6]C(-[:90,.6]H)(-[:0,.6]H)(-[:270,.6]H)} &

    it is centred but as yiou have forced all the columns to be the same width, entries with smaller structures have more space around them. (if you used |Y|Y|Y|Y| so it added rules it would be clearer that the table itself is centred but there is white space inside the first column

Since line breaking inside the cells is neither expected nor desirable, and since the natural widths of the four columns are quite different, using a tabularx environment seems wrong. I suggest you use a tabular* environment instead.
