space lost when converting inline cell to tex

Question

Sample Cell 1 words with spaces in one inline cell

Cell[TextData[Cell[BoxData[\(TraditionalForm\`\(Y\ =\ \(\({\(x\ \[Element]\ \([\(a,\ b\)]\)\)\ :\ \(there\ is\ a\ finite\ subcover\ in\ \(\[Sum]\ \(of\ the\ \(interval\ [\(a,\ x\)]\)\)\)\)}\) .\ \)\)\)], "InlineFormula", FormatType -> "TraditionalForm"]], "Text"]

When saving it as Tex, or Copy As Latex, the spaces between words will lost,

What's the right and good method to deal with such thing? The worst is each time this happen, I modify it in Tex Editor.

As Silva's answer suggested, creating text cell for inline words block. What occurred in my mind is to develop some palletes like this post(my prevous quesion) to do the similar thing. How to make AutoAction take effect only one time?

As you see in the picture, I'm handling the InlineFormula with blue color. In the biggest blue block, there are two words blockthere is a finite subcover in and of the interval. Consider one possible situation, there are five or more words block in the inline cell with depth 2.

Answer 1

I guess that is because you put your text all in an "InlineFormula" Cell, which is an equivalent to the LaTeX inline formula environment (i.e. $...$), so they are understand as many variables multiply together. And as you know, spaces between multipliers are omitted by default.

The following code works on my computer:

Cell[TextData[
   Cell[BoxData[FormBox[RowBox[{"Y", "=", RowBox[{"{", RowBox[{

            RowBox[{"x", "\[Element]", 
              RowBox[{"[", RowBox[{"a", ",", "b"}], "]"}]}],

            Cell[": there is a finite subcover in ", "Text"],

            "\[CapitalSigma]",

            Cell[" of the interval ", "Text"],

            RowBox[{"[", RowBox[{"a", ",", "x"}], "]"}]
            }], "}"}]}], TraditionalForm]]]], "Text"] // CellPrint

Then copy the printed cell into a new notebook and save it as TeX:

Render it with mathjax engine on this site:

$Y=\{x\in [a,b]\text{: there is a finite subcover in }\Sigma \text{ of the interval }[a,x]\}$
