I am working on an Elsevier Paper where I have to build up a table of notations. I have tried both {tabular} and {tabu} packages. But, in Tabular, table width exceeds the text block width while in Tabu, the table width matches the text width but I could not adjust the first column to get a smaller width to allow for the the other column to get most of the space. The codes are shown as follows:

Moreover, it may the table become larger than a page, and I may have to have a caption like Table 1 for the table on the first page, and for the one on the other page should have a title like Table 1 Cont'd.
I would really appreciate if you could help me out with the above-mentioned issues (table width matching the text block in {Tabular}, column width adjustment in {Tabu}, and long tables with one same name / label (Table 1, Table 1 cont/d) to be cross-referenced to as table 1.
