+
+A Better Decimal-Alignment Solution
+\layout Standard
+
+An alternative way to have decimal alignment in tables is through the dcolumn
+ package.
+ Add the following to the LateX preamble:
+\layout LyX-Code
+
+
+\backslash 
+usepackage{dcolumn} 
+\layout LyX-Code
+
+
+\backslash 
+newcolumntype{d}[1]{D{.}{.}{#1}}

+To have a column decimally aligned, enter in the

+Special Column Alignment
+\family default 
+ box of the 
+\family sans 
+Table extra
+\family default 
+ form the following:
+\layout LyX-Code
+
+d{number of decimals of the data}
+\layout Standard
+
+In the following table we entered

+\layout Standard
+
+To create extra column space just increase the number of decimals in 
+\family typewriter 
+d{}
+\family default 
+.
+ Setting the multicolumn attribute for a single cell makes it insensitive
+ to the decimal alignment which comes in handy as well.
+ A drawback of this method is that math mode is not allowed in a column
+ with decimal alignment except if the multicolumn attribute is set.
+\layout Standard
+
+This method offers the same flexibility as the 
+\family typewriter 
+dcolumn
+\family default 
+ package.
+ One could, for example, change the alignment separator, and have different
+ alignment separators for different columns by defining multiple column
+ types in the preamble.
+ The syntax is as follows: 
+\layout LyX-Code
+
+D{inputsep}{outputsep}{decimal places}
+\layout Standard
+
+The interested reader is directed towards the 
+\family typewriter 
+dcolumn
+\family default 
+ package documentation for more details.
