The next situatin is possible , if in moment when splitAt command HTML table not yet fully rendered or by any other reason has zero width, grid will calculate width of splited area as some percent from 0 ( which obviously will be also 0)
To prevent such error you can try to move grid initialization code to the end of page , or run it from onLoad event
If problem still occurs for you - please provide any kind of sample ( you can send it directly to
dhtmlx@scand.com )
